The aim of this pilot study was to evaluate the difference between using antibiotic-loaded hydrogel (ALH) and calcium sulphate (CS) beads in the DAIR procedure.

MicroRNA Expression Levels in Peripheral Blood Mononuclear Cells from Human Immunodeficiency Virus Type 1 Positive Individuals and Relationship with Different Levels of Viral Suppression.

The persistence of low human immunodeficiency virus type 1 (HIV-1) replication in individuals undergoing antiretroviral therapy (ART) still threatens their health. Previous findings have shown that microRNAs (miRNAs) could interfere with several steps of the viral life cycle. Herein, we set out to investigate the expression of miR-150, miR-223, miR-382, miR-324-5p, miR-33a-5p, miR-34a, and miR-132 in the whole peripheral blood mononuclear cell (PBMC) population from people living with HIV-1 showing different levels of viral suppression.

Chronic Suppressive Antibiotic Treatment for Staphylococcal Bone and Joint Implant-Related Infections.

Prosthetic joint infection (PJI) and fracture-related infection (FRI) are difficult-to-treat conditions in patients with severe comorbidity or significant surgical risk. In cases not eligible for standard strategy, debridement procedures with the retention of prosthesis or internal fixation device, combined with long-term antibiotic treatment and subsequent indefinite chronic oral antimicrobial suppression (COAS), can be the only reasonable choice. The aim of this study was to investigate the role of COAS and its follow-up in the management of these cases.
