has been classically used to treat diarrhea and diarrhea-related diseases. However, in the past two decades, fungal infections caused by have been increasing among immunocompromised patients, and it takes too long to isolate from blood to diagnose it in time. In this paper, a new method for the isolation and selection of from red blood cells (RBC) is proposed by designing a microfluidic chip with an optically-induced dielectrophoresis (ODEP) system. It was verified by theory and experiments that the magnitude and direction of the dielectrophoresis force applied on RBCs and are different, which determine that the can be isolated from RBCs by the ODEP system. By designing the specific light images and the dynamic separation mode, the optimal operating conditions were experimentally achieved for acquiring higher purity of . The purity ranges were up to 95.9%-97.3%. This work demonstrates a promising tool for efficient and effective purification of from RBCs and provides a novel method of isolation for the timely diagnosis of fungal infections.

January 2025
Beijing Institute of Ophthalmology, Beijing Tongren Eye Center, Beijing Tongren Hospital, Capital Medical University, Beijing, China.
Purpose: To clarify the clinical and imaging characteristics of Candida keratitis using in vivo confocal microscopy (IVCM) for improved early diagnosis and management.
Methods: A retrospective study of 40 patients with Candida keratitis at Beijing Tongren Hospital from January 2015 to December 2023 was conducted. Data included demographics, risk factors, clinical assessments, lab tests, and IVCM images.
Patient-centered outcomes for clinical trials in chronic rhinosinusitis with or without nasal polyps and allergic fungal rhinosinusitis.
J Patient Rep Outcomes
January 2025
Sanofi US Services, Inc., Bridgewater, NJ, USA.
Background: Chronic rhinosinusitis (inclusive of subtypes with nasal polyps [CRSwNP], without nasal polyps [CRSsNP], and allergic fungal rhinosinusitis [AFRS]) causes inflammation of the nose mucosa and paranasal sinuses. Unfortunately, evidence supporting use of clinical outcome assessments (COAs) in regulated clinical trials to assess key measurement concepts of these conditions is limited.
Objective: To identify key disease-related symptoms and impacts, potential outcomes of interest for new treatments, and COAs available to measure those outcomes among adult and adolescent individuals living with CRSwNP, CRSsNP, and AFRS.

January 2025
Departamento Micología-Instituto Nacional de Enfermedades Infecciosas "Dr. Carlos G. Malbrán", Buenos Aires, Ciudad Autónoma de Buenos Aires, Argentina.
Background: Epidemiological surveillance of Candidozyma sp. has become important because many species of this new genus have been reported to be responsible for nosocomial outbreaks and to exhibit elevated minimal inhibitory concentrations (MIC) to one or more classes of antifungal drugs.
Objectives: To describe the genetic relationships among Argentinian clinical isolates belonging to the Candidozyma genus and to study the molecular mechanisms associated with antifungal resistance.
Analysis of the relevant factors for corneal graft rejection in the southern Liaoning region from 2019 to 2023.

Dalian Medical University, Dalian, China.
Background: The study aimed to review the etiology of corneal blindness and investigate the relative risk of corneal graft rejection (CGR) in the southern Liaoning region.
Methods: The clinical records of 359 patients (394 eyes) who underwent corneal transplantation at the Department of Keratoconus of the Third People's Hospital of Dalian from January 2019 to December 2023 were retrospectively analyzed. The data included patients' age, gender, occupation, diagnosis, surgical procedure, postoperative immune rejection, and neovascularization.
