Effectiveness of clindamycin-based exposure strategies in experimental mature staphylococcal biofilms.
Microbiol Spectr

Center for Infectious Diseases, Lab of Infectious Diseases, Leiden University Medical Center, Leiden, the Netherlands.
Unlabelled: Due to increasing antimicrobial resistance and side effects caused by current standard antimicrobial regimens used for treatment of prosthetic joint infection (PJI), alternative options are urgently needed. We aimed to investigate the effect of clindamycin in different exposure strategies against in an mature biofilm model. In short, 7-day biofilms were generated on polystyrene plates and titanium-aluminum-vanadium discs using a clinical PJI isolate.

January 2025
Centro de Uro-Andrología S.C., Guadalajara, Jalisco.
Aim: To determine the effects of oral antibiotics and anti-inflammatory agents on semen parameters and the sperm DNA fragmentation index (DFI).
Methods: Ninety-eight men with infertility diagnosis were included. The participants submitted two semen samples, before and at least two months after treatment.
Introduction: Interventions aimed at preventing and treating maternal infections during the gestational period are of paramount importance. Timely immunizations, screening strategies and management of maternal infections reduce the risk of complications for the developing fetus and play a pivotal role in improving neonatal outcomes.
Summary: We summarize evidence for a total of thirteen interventions, pertaining to the prevention and treatment of maternal infections during the antenatal period, from Every Newborn Series published in The Lancet 2014.
Collagen silver-doped hydroxyapatite scaffolds reinforced with 3D printed frameworks for infection prevention and enhanced repair of load-bearing bone defects.

Osteomyelitis, a severe bone infection, is an extremely challenging complication in the repair of traumatic bone defects. Furthermore, the use of long-term high-dose antibiotics in standard treatment increases the risks of antibiotic resistance. Herein, an antibiotic-free, collagen silver-doped hydroxyapatite (coll-AgHA) scaffold reinforced with a 3D printed polycaprolactone (PCL) framework was developed with enhanced mechanical properties to be used in the repair of load-bearing defects with antimicrobial properties as a preventative measure against osteomyelitis.

Wastewater treatment plants (WWTPs) currently face major challenges toward the removal of microcontaminants and/or microbial matrices and consequently play an important role in the potential dissemination of biological resistance in freshwater. The ultraviolet (UV) system is a tertiary treatment strategy increasingly applied worldwide, although many studies have shown that disinfected effluent can still contain antibiotic-resistant bacteria and resistance genes. Therefore, to better understand the effects of UV radiation doses on the removal of all resistance elements (antibiotics, antibiotic-resistant bacteria, and antibiotic resistance genes), the present study was designed using a pilot-scale photoreactor.
