Article Abstract
Objectives: To evaluate in vitro activities of sitafloxacin and comparators against the clinical isolates of less common nonfermenting Gram-negative bacteria (NFGNB).
Methods: The isolates of less common NFGNB were collected during a long period spanning five years from 2016 to 2020 in Huashan Hospital, Fudan University in Shanghai. A broth microdilution method was used to determine the minimum inhibitory concentrations (MICs) of sitafloxacin and comparators.
Results: In terms of MIC values, sitafloxacin was highly active against Stenotrophomonas maltophilia (0.25/1 mg/L), Burkholderia cepacia complex (0.25/2 mg/L), Achromobacter xylosoxidans (0.25/1 mg/L), and Chryseobacterium gleum (1/2 mg/L), but less active for Elizabethkingia (1/8 mg/L) and Chryseobacterium indologenes (16/32 mg/L). Sitafloxacin was more active than other fluoroquinolones against these NFGNB except Chryseobacterium.
Conclusion: The results are helpful for clinicians to be aware of the role of sitafloxacin in managing the infections caused by these NFGNB.

Colorectal cancer (CRC) is one of the most common and lethal malignancies worldwide, with treatment failure often attributed to chemoresistance and evasion of apoptosis. Cathayanon E (CE), a natural chalcone derivative isolated from Morus alba, has shown anticancer potential, but its role and mechanism in CRC remain largely unexplored. In this study, CE significantly inhibited CRC cell proliferation and induced apoptosis both in vitro and in vivo.

Betel quid chewing is a culturally-rooted oral health risk behavior that is prevalent in many Southeast Asian communities. Among Malaysia's indigenous community, particularly in isolated areas, data on betel quid chewing remain limited. This study investigated the influencing factors and health perceptions of betel quid use among 180 adults from a Proto-Malay Orang Asli community in Peninsular Malaysia.

Two recent Phase 3 trials demonstrated the efficacy of gepotidacin compared with nitrofurantoin to treat uncomplicated urinary tract infections (uUTIs) in females. Pretreatment urine specimens were obtained from all participants. Based on pooled trial data (treatment groups combined), central laboratory culture results identified 1,421 (45%) participants with ≥1 baseline qualifying (≥10 CFU/mL) uropathogen (i.

It is a gram-positive anaerobic bacteria or microaerobic filamentation bacteria, which can induce pyogenic and granulomatous inflammation characterized by swelling and concomitant pus, sinus formation, and the formation of yellow sulfur granules. All tissues and organs can be infected; the most common type involves the neck and face (55%), followed by the abdominal and pelvic cavities (20%).

Purpose: To define the genetic architecture of foveal morphology and explore its relevance to foveal hypoplasia (FH), a hallmark of developmental macular disorders.
Methods: We applied deep-learning algorithms to quantify foveal pit depth from central optical coherence tomography (OCT) B-scans in 61,269 UK Biobank participants. A genome-wide association study (GWAS) was conducted using REGENIE, adjusting for age, sex, height, and ancestry.
