"The Slums Have To Be Shown": Documenting Drug Injection in Public Spaces Ahead of the Opening of a Drug Consumption Room in Marseille.

EPOSIM is a community-based participatory research study which used the Photovoice method with people who inject drugs (PWID) ahead of a possible opening of a drug consumption room (DCR) in Marseille, France. It aimed to identify the strategies used by PWID when injecting, and the risks they take when they have no safe private space to inject in the area they live in. A total of 7 PWID participated in the full study process. The 189 photographs they took provided us with a good understanding of their injection practices in public places. The main results highlighted the spatiality and materiality of injecting experience in a context where no DCR was available. They also showed the relevance of Photovoice to valorize the voices of PWID when implementing a DCR. Through the showcasing of their photographs at various public exhibitions, the participants seized the opportunity to use Photovoice to make their voices heard beyond the group formed for the study, in order to show the different forms of stigma and insalubrious contexts which they faced on a daily basis. Furthermore, the photographs taken demonstrated that having only health and safety records is not enough to fully understand PWID injection practices. Future studies must take into account PWID perceptions of their relationship with injecting in public spaces and with the management of stigma. The questions of pleasure and comfort must also be explored in evaluation studies of harm reduction measures, for example, DCR.

Accuracy and potential usefulness of triplex real-time PCR for improving antibiotic treatment of patients with blood cultures showing clustered gram-positive cocci on direct smears.

Bacterial identification and antibiotic susceptibility testing currently require 48 h when a first blood culture (BC) is positive for clustered gram-positive cocci on direct smear examination (DSE). Meanwhile, antibiotic treatment is often inadequate, reducing the chances of effective treatment or creating unnecessary selective pressure. A new real-time PCR (RT-PCR) technique that differentiates Staphylococcus aureus from coagulase-negative staphylococci (CoNS) and detects methicillin resistance in 90 min in BC bottles could help solve these problems. BC bottles from 410 patients with gram-positive cocci on DSE were processed by current methods, and patients' treatments were prospectively recorded. The RT-PCR assay was performed on aliquots of these BCs, which had been kept frozen. For the 121 patients who had true bacteremia, we established whether the faster availability of RT-PCR results could have led to the initiation of treatments different from those actually given. RT-PCR sensitivity and specificity were 100% for differentiating between S. aureus and CoNS and detecting methicillin resistance with two manufacturers' BC bottles. For 31/86 (36%) of the S. aureus-infected patients and for 8/35 (23%) of the CoNS-infected patients who either had suboptimal or nonoptimal treatment or were untreated 48 h after positivity was detected, the early availability of RT-PCR results could have allowed more effective treatment. Unnecessary glycopeptide treatments could have been avoided for 28 additional patients. The use of RT-PCR would increase treatment effectiveness in patients with staphylococcal bacteremia and reduce the selective pressure created by glycopeptides.
