Fiocruz as an actor in Brazilian foreign relations in the context of the Community of Portuguese-Speaking Countries: an untold story / A Fiocruz como ator da política externa brasileira no contexto da Comunidade dos Países de Língua Portuguesa: uma história revelada

Brazilian foreign policy paradigms and changes in the global scenario since the Cold War created conditions for stronger ties between Brazil and Portuguese-speaking African countries. Recently, Brazil took the lead in regional integration processes and in South-South cooperation initiatives. These strategies and Fiocruz's acknowledged technical expertise resulted in its direct involvement in Brazilian foreign public health policy in the Community of Portuguese-Speaking Countries. Fiocruz developed cooperation projects in various areas, sharing its know-how and best practices in the most critical fields in partner countries, consolidating "public health framework cooperation" and contributing to diversifying Brazil's partners and promoting Brazil as a global actor.

Os paradigmas da política externa brasileira e as mudanças no cenário global desde a Guerra Fria criaram as condições para aproximação do Brasil com os países africanos de língua portuguesa. Recentemente, o Brasil tomou a liderança nos processos de integração regional e nas iniciativas de cooperação Sul-Sul. Essas estratégias e a reconhecida expertise técnica da Fiocruz abriram espaço para o envolvimento direto da instituição na política externa do Brasil com a Comunidade de Países de Língua Portuguesa na área da saúde. A Fiocruz desenvolveu projetos de cooperação em áreas diversas, compartilhando seu know-how e melhores práticas em áreas prioritárias dos países parceiros, consolidando a "cooperação estruturante em saúde" e contribuindo para a diversificação de parceiros do país e promovendo o Brasil como ator global.

Clinicopathological Features and Differences of p53 and Ki-67 Expression in Adenosquamous and Squamous Cell Carcinomas of the Stomach / 대한소화기학회지

BACKGROUND/AIMS: This study reviewes the clinicopathological features, prognosis, and differences in the expression of p53 and Ki-67 immunochemical staining in squamous cell and adenosquamous carcinoma of the stomach. METHODS: From January 1995 to June 2005, 2,282 cases of gastric carcinoma were resected surgically in our hospital and 191 additional cases were resected by endoscopic mucosal resection. Retrospective pathologic review and immunochemical staining of p53 and Ki-67 were performed. RESULTS: The study consists of eight cases (0.032%) of primary squamous cell carcinoma (one case) and adenosquamous carcinoma (seven cases) without early gastric cancer. Six cases (75.0%) were male and two cases were female. The mean age was 66 year-old. The clinical presentation and physical findings did not differ from those of adenocarcinoma. The mean tumor size was 5.2+/-1.7 cm. Macroscopically, five were Borrmann type 3 (62.5%) and three were type 2. At the initial diagnosis, six (75%) were stage IV based on TNM tumor staging. Six cases (75%) progressed despite the therapy while two cases responded to the treatment. The median survival time was 11.0 months (range 4.3+/-17.7). Overexpression of p53 was seen in five cases (62.5%) and their survival was poor when compared to the p53-negative group (p=0.04). The mean Ki-67 labeling index was 70.0+/-20.8%, and was not associated with p53 staining (p>0.05). CONCLUSIONS: Adenosquamous and squamous cell carcinoma of the stomach are very rare. They tend to be at advanced stages on initial diagnosis, and progress rapidly. They show p53 protein overexpression and high Ki-67 labeling index, which might be related to poor prognosis.
