Cancer Medicine, Volume 11, Issue 24, Page 4849-4864, December 2022., 2022 In clinical settings, many NSCLC patients undergo antibiotic treatment prior to the initiation of chemotherapy. Previous studies have reported that antibiotic use can affect the efficacy of immunotherapeutic treatment regimens. Whether antibiotics similarly impact chemotherapy efficacy, however, remains to be established.

Occurrence of beta-lactamases in bacteria
Infection, Genetics and Evolution, 2023 Our study highlights the escalating issue of beta-lactam resistance in nosocomial pathogens, driven by the broad spectrum of antibiotic-degrading enzymes and plasmid exchange. We catalogued known beta-lactamases across 230 bacterial genera, identified 2349 potential beta-lactamases across over 673 genera, and anticipate discovering many new types ...

Hematological Oncology, Volume 40, Issue 5, Page 846-856, December 2022., 2022 Abstract The impact of secondary infections (SI) on COVID‐19 outcome in patients with hematological malignancies (HM) is scarcely documented. To evaluate incidence, clinical characteristics, and outcome of SI, we analyzed the microbiologically documented SI in a large multicenter cohort of adult HM patients with COVID‐19.
