OBJECTIVES: HIV infection and exposure to certain antiretroviral drugs is associated with dyslipidemia and increased risk for coronary events. Whether this risk is mediated by highly atherogenic lipoproteins is unclear. We investigated the association of highly atherogenic small dense low-density lipoproteins (LDLs) and apolipoprotein B and coronary events in HIV-infected individuals receiving antiretroviral therapy. METHODS: We conducted a case-control study nested into the Swiss HIV Cohort Study to investigate the association of small dense LDL and apolipoprotein B and coronary events in 98 antiretroviral drug-treated patients with a first coronary event (19 fatal and 79 nonfatal coronary events with 53 definite and 15 possible myocardial infarctions, 11 angioplasties or bypasses) and 393 treated controls matched for age, gender, and smoking status. Lipids were measured by ultracentrifugation. RESULTS: In models including cholesterol, triglycerides, high-density lipoprotein cholesterol, blood pressure, central obesity, diabetes, and family history, there was an independent association between small dense LDL and coronary events [odds ratio (OR) for 1 mg/dL increase: 1.06, 95% confidence interval (CI): 1.00 to 1.11] and apolipoprotein B (OR for 10 mg/dL increase: 1.16, 95% CI: 1.02 to 1.32). When adding HIV and antiretroviral therapy-related variables, ORs were 1.04 (95% CI: 0.99 to 1.10) for small dense LDL and 1.13 (95% CI: 0.99 to 1.30) for apolipoprotein B. In both models, blood pressure and HIV viral load was independently associated with the odds for coronary events. CONCLUSIONS: HIV-infected patients receiving antiretroviral therapy with elevate small dense LDL and apolipoprotein B are at increased risk for coronary events as are patients without sustained HIV suppression.

Aquesta ponència reflexiona sobre el concepte i l'evolució de la recerca i el desenvolupament (R+D) en investigació literària als territoris de llengua i cultura catalanes. Des de punts de vista quantitatius i qualitatius, s'examinen els agents de recerca involucrats (universitats, instituts i grups de recerca, fundacions, etc.) i els recursos invertits (humans, econòmics i materials), així com els resultats obtinguts (monografies i capítols, revistes i articles, tesis doctorals, comunicacions de congressos, etc.). Les dades s'han obtingut de diverses fonts d'informació, fet que evidencia els importants problemes metodològics en la seva recollida (manca de reculls objectius i sistemàtics, treball manual per recopilar i organitzar la informació adient, etc.). Sempre que és possible, la informació s'estudia segons les diferents àrees geogràfiques i àmbits d'especialització (literatura contemporània; literatura moderna; literatura medieval; i, finalment, estudis transversals i de teoria de la literatura i literatura comparada). Per acabar, s'extreuen algunes conclusions sobre la R+D literària i les seves perspectives de futur.
