Personalidade e câncer de mama: produção científica em Psico-Oncologia

O presente estudo se insere no campo da Psico-Oncologia. Objetivou-se empreender uma revisão sistemática da literatura científica dedicada especificamente ao papel da personalidade na evolução da condição clínica e emocional de mulheres acometidas por câncer de mama. Foram consultadas as bases de dados MedLine, PsycINFO, LILACS, SciELO-Brasil e PePSIC. De modo geral, os achados das referências selecionadas apontam que o otimismo enseja uma evolução mais favorável da condição emocional. Além disso, sustentam que pacientes com espírito de luta e manejo apropriado da ansiedade desencadeada por estímulos agressivos tendem a uma melhor condição clínica. Todavia, sugere-se a utilização, em futuras investigações, de escolhas teórico-metodológicas inovadoras para o avanço do conhecimento que atualmente se tem a respeito do assunto em pauta

Combination antiretroviral therapy and the risk of myocardial infarction RID C-2464-2008 RID B-4427-2008 RID H-3944-2011 RID B-5656-2009 RID E-7045-2010 RID A-1057-2008

Background: It remains controversial whether exposure to combination antiretroviral treatment increases the risk of myocardial infarction. Methods: In this prospective observational study, we enrolled 23,468 patients from 11 previously established cohorts from December 1999 to April 2001 and collected follow-up data until February 2002. Data were collected on infection with the human immunodeficiency virus and on risk factors for and the incidence of myocardial infarction. Relative rates were calculated with Poisson regression models. Combination antiretroviral therapy was defined as any combination regimen of antiretroviral drugs that included a protease inhibitor or a nonnucleoside reverse transcriptase inhibitor. Results: Over a period of 36,199 person-years, 126 patients had a myocardial infarction. The incidence of myocardial infarction increased with longer exposure to combination antiretroviral therapy (adjusted relative rate per year of exposure, 1.26 [95 percent confidence interval, 1.12 to 1.41]; P<0.001). Other factors significantly associated with myocardial infarction were older age, current or former smoking, previous cardiovascular disease, and male sex, but not a family history of coronary heart disease. A higher total serum cholesterol level, a higher triglyceride level, and the presence of diabetes were also associated with an increased incidence of myocardial infarction. Conclusions: Combination antiretroviral therapy was independently associated with a 26 percent relative increase in the rate of myocardial infarction per year of exposure during the first four to six years of use. However, the absolute risk of myocardial infarction was low and must be balanced against the marked benefits from antiretroviral treatment
