TL;DR: The tests conducted showed high prevalence and incidence rates of HIV and hepatitis B/C among patients who had consumed intravenous drugs for years, and descriptive analysis in heroin-assisted treatment showed a reduction in infection risk for viral hepatitis corresponding to the lower risk behaviour of patients.

TL;DR: While inclusion of a volumetric collagen scaffold led to repair failure, use of FibGen alone demonstrated clinically relevant promise for prevention of mechanical reherniation, outperforming an FDA approved sealant in this ex vivo test series.

TL;DR: During treatment, a significant reduction in risk-taking behavior was observed in a target population of heroin-dependent persons who failed in previous treatments, and this confirms that a group of drug dependence with severe medical problems was reached in accordance with the admission criteria for the studies.
