Results from an intercomparison of several currently used in-situ techniques for the measurement of atmospheric formaldehyde (CH 2 O) are presented. The measurements were carried out at Bresso, an urban site in the periphery of Milan (Italy) as part of the FORMAT-I field campaign. Eight instruments were employed by six independent research groups using four(More)
BACKGROUND The number of patients on second-line highly active antiretroviral therapy (HAART) regimens is increasing in resource-limited settings. We describe the outcomes after 24 months for patients on LPV/r-based second-line regimens followed up by the ESTHER programme in Phnom Penh, Cambodia. METHODS Seventy patients who initiated second-line HAART(More)
Early (2 weeks) vs. late (8 weeks) initiation of highly active antiretroviral treatment (HAART) significantly enhance survival of severely immunosuppressed HIV-infected adults with newly diagnosed tuberculosis: results of the CAMELIA clinical trial Background Tuberculosis (TB) remains the largest cause of death among people living with HIV/AIDS, especially(More)
BACKGROUND Tuberculosis remains an important cause of death among patients infected with the human immunodeficiency virus (HIV). Robust data are lacking with regard to the timing for the initiation of antiretroviral therapy (ART) in relation to the start of antituberculosis therapy. METHODS We tested the hypothesis that the timing of ART initiation would(More)
BACKGROUND Shortening the interval between antituberculosis treatment onset and initiation of antiretroviral therapy (ART) reduces mortality in severely immunocompromised human immunodeficiency virus (HIV)-infected patients with tuberculosis. A better understanding of causes and determinants of death may lead to new strategies to further enhance survival.(More)
There are few long-term data on ART-experienced patients in resource-limited settings. We performed a cross-sectional study of HIV-infected patients included in the ESTHER program in Calmette hospital, Phnom Penh, Cambodia, after 36 ± 3 months of cART. Therapeutic, clinical, and immunovirological outcomes were compared between patients who stated they were(More)
In 2009, we conducted a case-control study to explore the routes of HCV transmission in people living with HIV/AIDS (PLHIV) in Cambodia. Cases were HCV/HIV co-infected patients (who tested RT-PCR positive for HCV-RNA or had confirmed presence of HCV antibodies) (n = 44). Controls were HIV mono-infected patients, with no HCV antibodies (n = 160). They were(More)
INTRODUCTION In resource limited settings, patients entering an antiretroviral therapy (ART) program comprise ART naive and ART pre-treated patients who may show differential virological outcomes. METHODS This retrospective study, conducted in 2010-2012 in the HIV clinic of Calmette Hospital located in Phnom Penh (Cambodia) assessed virological failure(More)

As part of the EU project FORMAT (Formaldehyde as a Tracer of Oxidation in the Tro-posphere), a field campaign was carried out in the vicinity of Milan during the summer of 2002. Results from a 3-D regional chemical transport model (NILU RCTM) were used to interpret the observations focusing primarily on HCHO and ozone. The per-5 formance of the model was(More)
