The influence of antibiotics, namely doxycycline, gentamicin, penicillin, nitrofurantoin, and rifampicin, on wastewater treatment was assessed. The presence of 100-300 μg/L of antibiotics (63.52-134.41 mg/g.d.w·d) marginally influenced organic matter degradation, without impacting nitrogen or phosphorus concentrations. However, a significant increase in the number of antibiotic-resistant bacteria was observed, which varied with different antibiotics. The largest number of bacteria became resistant to nitrofurantoin and penicillin...

Vancomycin-resistant enterococci (VRE) are a growing healthcare concern, and since 2012 the incidence has increased eightfold in Denmark. Treatment options for infections with ampicillin-resistant VRE are sparse, and there are no Danish guidelines concerning this topic. For treatment of uncomplicated VRE urinary tract infections, ciprofloxacin or nitrofurantoin can be used. The mainstay of treatment of bacteraemia and other severe infections caused by VRE is linezolid or high-dose daptomycin. Combination treatment is recommended for complicated infections and/or prolonged therapy...

INTRODUCTION: Single institution studies suggest a benefit of a week of preoperative antibiotics prior to percutaneous nephrolithotomy (PCNL). These studies are limited by lower quality methodology such as the inclusion of heterogeneous populations or the use of non-standard definitions of sepsis. The American Urological Association (AUA) Best Practice Statement recommends <24 hours of IV antibiotics, but no other data exist about the duration/benefit of preoperative antibiotics. We sought to perform a rigorous (using CONSORT guidelines), multi-institutional trial to assess preoperative antibiotics in PCNL patients at low risk of developing infections...
