METHODS Antiretroviral-naïve HIV-1-infected individuals newly enrolled in the FHDH cohort between 2002-2010, with CD4 cell counts >200/μL and no previous(More)
BACKGROUND To test the prognostic value of tumour protein and genetic markers in colorectal cancer (CRC) and examine whether deficient mismatch repair (dMMR) tumours had a distinct profile relative to proficient mismatch repair (pMMR) tumours. METHODS This prospective multicentric study involved 251 stage I-III CRC patients. Analysed biomarkers were EGFR(More)
Objectives To compare virological outcomes in patients who switched to a cART including efavirenz (EFV), nevira-pine (NVP) or abacavir (ABC) with patients who continued on a first virologically successful boosted protease inhibitor (PI)-containing cART, and to assess virological differences between the switch regimens. Methods Using the French Hospital(More)
