In an open prospective study, the efficacy and tolerability of ofloxacin in the treatment of chronic post-traumatic osteitis was examined in 83 patients. 103 different pathogens were isolated. More than 75% were Gram-positive bacteria with Staphylococcus aureus occurring in 61% of cases. After ofloxacin treatment bacteriological elimination was more than 90% for both Gram-positive and Gram-negative species, leading to a clinical cure in 85% of patients. Reinfection occurred in 5% of patients. These values were obtained from follow-up examinations which were carried out at least 6 months after the end of therapy. The tolerability of ofloxacin was excellent and no drug-related allergic reactions or side effects were observed. In conjunction with adequate surgical treatment, ofloxacin proved to be a useful antibacterial agent in the therapy of chronic bone infection.

The impact of heteroresistance on tuberculosis (TB) treatment outcomes is unclear, as is the role of different rifampin and isoniazid exposures on developing resistance mutations. Hollow fiber system model of TB (HFS-TB) units were inoculated with drug-susceptible () and treated with isoniazid and rifampin exposure identified in a clinical trial as leading to treatment failure and acquired drug resistance. Systems were sampled for drug concentration measurements, estimation of total and drug-resistant , and small molecule overlapping reads (SMOR) analysis for the detection of heteroresistance.

Compared with uncomplicated urinary tract infections (UTIs), complicated UTIs (cUTIs) including acute pyelonephritis (AP) present with significant morbidity, a higher risk of treatment failure and typically require longer courses of treatment, or alternative antibiotics. The emergence of drug-resistant organisms represents a considerable challenge in the treatment of patients with cUTIs/AP and has limited antibiotic options. Carbapenems are considered the current last line of therapy, however, carbapenem resistance represents a growing problem.

This study investigates the discharge of pharmaceuticals and personal care products (PPCPs) from wastewater treatment plants (WWTPs) into natural waters, highlighting a significant correlation with regional human activities. Despite the complexity of assessing factors influencing PPCPs sources, it remains underexplored. By conducting an extensive literature review of seven categories of PPCPs in WWTPs across five typical regions of China, the study reveals both similarities and disparities in PPCPs composition.

Elevated concentrations of pharmaceutically active compounds (PhACs) in the water bodies are posing a serious threat to the aquatic microbiota and other organisms. In this context, anaerobic ammonium oxidizing (anammox) bacteria carry a great potential to degrade PhACs through their innate metabolic pathways. This study investigates the influence of short-term exposure to lower and higher concentrations (0.

Cadmium is a non-essential element and neurotoxin that causes neuroinflammation, which leads to neurodegenerative diseases and brain cancer. To date, there are no specific or effective therapeutic agents to control inflammation and alleviate cadmium-induced progressive destruction of brain cells. Fluoroquinolones (FQs), widely used antimicrobials with effective blood-brain barrier penetration, show promise in being repurposed as anti-inflammatory drugs.
