Methods We performed a retrospective study on 45 patients, intravenous drug users (IVDU), diagnosed with HIV infection between 01 December 2010 – 01 August 2013 (30 months), in our department for HIV/AIDS infection in the Clinical Hospital of Infectious and Tropical Diseases “Dr. Victor Babeş” in Bucharest. All of these patients were also diagnosed and(More)

This happened in our country too, where a new way to get started HIV appeared: intravenous drugs used of so-called soft, legal drugs (ethnobotanicals) near the classic heroin.

Heroin use and the new ethnobotanic drugs (so called “legal drugs”) led to a dramatic increase in mortality in these intravenous drug users (IVDUs). A European multicentre study showed how IVDUs with recent HIV seroconversion are(More)

In this paper, we present a simple way to estimate probabilities of symbols occurring in a given sequence by considering the context where they appear. Every statistical adaptive compression method can use those estimation to encode a given sequence. The main goal is to find convenient estimation models which assign to every symbol in the sequence a(More)
During the last few years in Romania, increased numbers of new HIV infections among ethnobotanicals intravenous drug users (eIVDU) were observed. Although most cases have relatively good immunological status, some patients reclaim antiretroviral (ARV) treatment because of very low CD4 count, severe comorbidities and/or pregnancies despite difficulties(More)
