Unlabelled: This study aimed to assess the efficacy of ceftazidime-avibactam (CZA) in combination with various antimicrobial agents against carbapenem-resistant (CRKP). We selected 59 clinical CRKP isolates containing distinct drug resistance mechanisms. The minimum inhibitory concentrations (MICs) of meropenem (MEM), colistin (COL), eravacycline (ERA), amikacin (AK), fosfomycin (FOS), and aztreonam (ATM), both individually and in combination with CZA, were tested using the checkerboard method.

It is an opportunistic pathogen that often infects people with compromised immune systems. It could invade human body through respiratory tract or skin wounds, cause local infection, and affect other organs via hematogenous dissemination.

Notable increases of azole resistance have been observed in this species, particularly within Asia-Pacific regions. Here, we carried out a genetic population study on 1571 global C.

Enhancing T cell activity while maintaining the tumor specificity of TCEs is the key to improving their clinical efficacy. However, currently, there needs to be more effective strategies in clinical practice.

Methods: A total of 2,926 bacterial and fungal strains were identified in samples collected from 1,679 patients with IAIs at the Peking Union Medical College Hospital between 2011 and 2021. Pathogenic bacteria and fungi were identified using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.
Ceftolozane/tazobactam (an antipseudomonal cephalosporin) in combination with a well-established β-lactamase inhibitor has not been approved to date in clinical practice in China. The aim of this study was to evaluate the in-vitro activity of ceftolozane/tazobactam and comparator agents against Pseudomonas aeruginosa with various resistance patterns. P.

Methods: This study performed in nine operating rooms and among 25 anesthesiologists at a cancer hospital. Sampling of the hands of anesthesiologists and the anesthesia environment was performed at a ready-to-use operating room before patient contact began and after decontamination.
The use of morphology to diagnose invasive mould infections in China still faces substantial challenges, which often leads to delayed diagnosis or misdiagnosis. We developed a model called XMVision Fungus AI to identify mould infections by training, testing, and evaluating a ResNet-50 model. Our research achieved the rapid identification of nine common clinical moulds: complex, complex, complex, complex, , , , spp.

A Gram-negative, non-motile rod and strictly aerobic bacterium, designated as 18B16333, was isolated from vertebral puncture tissue of a patient at Peking union medical college hospital in China. Growth occurred in NaCl concentrations of 0-1% (w/v) (optimum growth at 0% NaCl), at temperatures of 25-40 °C (optimum growth at 37 °C) and at pH 6.0-9.

Methods: In this cross-sectional survey, 1,912 healthcare providers and oncologists were surveyed anonymously using 16 questions carried out at community oncology practices in China from September 2018 to April 2021. 16 questions were designed to evaluate their knowledge on male fertility preservation in cancer patients, assess the factors they considered when deciding whether to discuss male fertility preservation with their patients.
Recently, the prevalence of macrolide-resistant has been reported, especially among Chinese children. The fitness cost of resistance is reported to render the resistant bacteria less virulent. To investigate the correlation between macrolide susceptibility of and pathogenicity, the whole genome of 70 isolates belonging to four clonal complexes with different macrolide susceptibilities was sequenced.

We collected 493 heparin anticoagulant samples from patients undergoing blood culture in Peking Union Medical College Hospital from November 2020 to March 2021. The PGN, LPS, and BDG in the plasma were detected using an automatic enzyme labeling analyzer, GLP-F300.

It can also determine the type of infection, which helps with clinical diagnosis and treatment, and guides the use of medication.

Antifungal resistance is frequent in molds, frequently leading to invasive mold infections (IMIs) in immunocompromised patients with high morbidity and mortality. Limited availability of effective antifungals for treatment of IMIs in China is an enormous challenge.
