Comércio, bens de prestígio e insígnias de poder: as agências centro-ocidentais africanas nos relatos de viagem de Henrique de Carvalho em sua expedição à Lunda (1884-1888)

Ao longo da segunda metade do século XIX, a região da África Centro-Ocidental foi palco do processo de intensificação de expedições europeias rumo ao interior do continente que conjugavam interesses econômicos, políticos e científicos. Esta pesquisa busca analisar o papel de relevo ocupado pela cultura material na agenda científica da expedição portuguesa à Lunda chefiada pelo militar português Henrique de Carvalho entre 1884 e 1888. Pretendemos também avaliar as potencialidades que o estudo sobre os objetos apresentam enquanto fontes para a compreensão mais ampla acerca das agências históricas africanas. Para tanto, selecionamos as obras Descripção da Viagem à Mussumba do Muatiânvua (1890-1894) e Ethnographia e História Tradicional dos Povos da Lunda (1890) e, de maneira complementar, o Album da Expedição ao Muatianvua (1887) e o catálogo Collecção Henrique de Carvalho (Expedição à Lunda), editado pela Sociedade de Geografia de Lisboa (1896). Assim, pela ótica da história social, pretendemos investigar como as exigências e predileções centro-africanas por determinados artigos moldaram as relações comerciais travadas nesse período, abordando os processos de incorporação e ressignificação de objetos particularmente, bens de prestígio e insígnias de poder - interpretados como expressões de identidades, códigos sociais e hierarquias políticas no âmbito dessas sociedades e de suas relações com os europeus.

Quality of pharmaceutical advertising and gender bias in medical journals (1998-2008): a review of the scientific literature

Objective: To review the scientific literature on pharmaceutical advertising aimed at health professionals in order to determine whether gender bias has decreased and the quality of information in pharmaceutical advertising has improved over time. Methods: We performed a content analysis of original articles dealing with medical drug promotion (1998-2008), according to quality criteria such as (a) the number, validity and accessibility of bibliographic references provided in pharmaceutical advertising and (b) the extent to which gender representations were consistent with the prevalence of the diseases. Databases: PUBMED, Medline, Scopus, Sociological Abstract, Eric and LILACS. Results: We reviewed 31 articles that analyzed advertising in medical journals from 1975-2005 and were published between 1998 and 2008. We found that the number of references used to support pharmaceutical advertising claims increased from 1975 but that 50% of these references were not valid. There was a tendency to depict men in paid productive roles, while women appeared inside the home or in non-occupational social contexts. Advertisements for psychotropic and cardiovascular drugs overrepresented women and men respectively. Conclusions: The use of bibliographic references increased between 1998 and 2008. However, representation of traditional male-female roles was similar in 1975 and 2005. Pharmaceutical advertisements may contribute to reinforcing the perception that certain diseases are associated with the most frequently portrayed sex.

Does the scientific evidence support the advertising claims made for products containing Lactobacillus casei and Bifidobacterium lactis? A systematic review

Background To analyse the scientific evidence that exists for the advertising claims made for two products containing Lactobacillus casei and Bifidobacterium lactis and to conduct a comparison between the published literature and what is presented in the corporate website. Methods Systematic review, using Medline through Pubmed and Embase. We included human clinical trials that exclusively measured the effect of Lactobacillus casei or Bifidobacterium lactis on a healthy population, and where the objective was related to the health claims made for certain products in advertising. We assessed the levels of evidence and the strength of the recommendation according to the classification criteria established by the Oxford Centre for Evidence Based Medicine (CEBM). We also assessed the outcomes of the studies published on the website that did not appear in the search. Results Of the 440 articles identified, 16 met the inclusion criteria. Only four (25%) of these presented a level of evidence of 1b and a recommendation grade of A, all corresponding to studies on product containing Bifidobacterium lactis, and only 12 of the 16 studies were published on the corporate website (47). Conclusions There is insufficient scientific evidence to support the health claims made for these products, especially in the case of product containing Lactobacillus casei.
