Purpose: To evaluate the value of calcofluor white in the diagnosis of invasive fungal disease (IFD).
Methods: A total of 84 patients with possible pulmonary fungal infection who underwent bronchoscopy with bronchoalveolar lavage fluid (BALF) were included. All BALF specimens were subjected to Calcofluor white (CFW), potassium hydroxide (KOH) and Gram stains.
Results: CFW has the most sensitivity than KOH and Gram staining. The specificity of CFW was 92.00 %, which was lower than that of Gram staining. The PPVs for CFW, KOH and Gram staining were 94.44 %, 84.62 % and 80.00 % respectively. The NPVs for CFW, KOH and Gram staining was 47.92 %, 32.39 % and 30.38 % respectively. The AUCs of these three methods were 0.748, 0.550 and 0.510 respectively.
Conclusion: CFW is superior to KOH and Gram staining in the diagnosis of invasive fungal diseases.

Microplastics (MPs) pollution has received widespread attention in recent years as the use of plastics continues to increase. However, currently no studies have reported the finding of MPs in human uterine fibroids (UFs) and myometrium tissues. In this study, UFs tissues (n = 48) and myometrium tissues (n = 40) from 48 patients and myometrium tissues (n = 8) from healthy population were collected.
