Risk for non-AIDS-defining and AIDS-defining cancer of early versus delayed initiation of antiretroviral therapy
BACKGROUND: Immediate initiation of antiretroviral therapy (ART) regardless of CD4 cell count reduces risk for AIDS and non-AIDS-related events in asymptomatic, HIV-positive persons and is the standard of care. However, most HIV-positive persons initiate ART when their CD4 count decreases below 500 × 10 9 cells/L. Consequences of delayed ART on risk for non-AIDS-defining and AIDS-defining cancer, one of the most common reasons for death in HIV, are unclear. OBJECTIVE: To estimate the long-term risk difference for cancer with the immediate ART strategy.DESIGN: Multinational prospective cohort study.SETTING: The D:A:D (Data collection on Adverse events of anti-HIV Drugs) study, which included…
Intra-skeletal variability in trace elemental content of Precolumbian Chupicuaro human bones: the record of post-mortem alteration and a tool for palaeodietary reconstruction.
14 pages; International audience; This study applies an intra-skeletal sampling strategy to examine post-mortem alteration of archaeological human bone from west Mexico, and to reconstruct ancient diet. Human bone from the Chupicuaro culture (Mexico, Preclassic period) constitutes an ideal material with which to examine subsistence strategies because the specific hydrothermal environment in which the population lived would have provided certain food components (hydrothermal waters and carbonates) with distinct signature in Ca, Mg, F, Li, Sr, Mn, V and U values. Four to ten samples were taken from the long bones of six skeletons. Bone trace element content (Ca, P, F, Mn, Mg, Na, Li, V, Zn, R…
Syndrome MIRAGE : données cliniques et biologiques chez 8 patients mutés pour le gène SAMD9
Objectifs Le syndrome myelodysplasia, infection, restriction of growth, adrenal hypoplasia, genital phenotypes and enteropathy (MIRAGE) est du a des mutations de novo du gene SAMD9. L’objectif etait de rechercher des mutations dans une cohorte de patients avec retard de croissance in utero (RCIU), insuffisance surrenale (IS) et/ou anomalie du developpement genitosexuel (DSD) et de caracteriser leur phenotype gonadique et surrenalien. Methode Sequencage Sanger de SAMD9 chez 20 patients. Resultats Le syndrome de 8 patients a pu etre explique par des mutations faux-sens SAMD9 (4 nouvelles). Celui-ci etait generalement complet avec chez certains des signes additionnels : reins hypoplasiques, de…
