Article Synopsis
  • Cryptococcus is a pathogenic fungus that mainly causes fungal meningitis, and the study assessed the effectiveness of the FungiXpert lateral flow assay (LFA) for diagnosing cryptococcosis using serum and cerebrospinal fluid samples.
  • In comparison with the FDA-approved IMMY CrAg LFA, FungiXpert LFA showed high sensitivity (99.1%) and specificity (98.9%) in detecting cryptococcal antigens.
  • Both assays exhibit cross-reactivity with the fungus Trichosporon asahii, highlighting the need for caution when interpreting results, while FungiXpert LFA serves as an effective and rapid method for diagnosing and treating cryptococcosis.

Defensive behavior, a group of responses that evolved due to threatening stimuli, is crucial for animal survival in the natural environment. For defensive measures to be timely and successful, a high arousal state and immediate sleep-to-wakefulness transition are required. Recently, the glutamatergic basal forebrain (BF) has been implicated in sleep-wake regulation; however, the associated physiological functions and underlying neural circuits remain unknown.

Objective: The climatic characteristics of aneurysmal subarachnoid hemorrhage (aSAH) have been reported, but consensus has not yet been reached. It is of great significance to elucidate the relationships between meteorological variation and aSAH in regions with specific climate patterns. We analyzed the occurrence of aSAH in the capital city of Fujian Province, China, through a multicenter, 5-year study, and aimed to reveal the meteorological influences on aSAH in the coastal city of eastern Fujian under the subtropical marine monsoon condition.

The bidirectional communication between the central nervous system (CNS) and the gut microbiota plays a pivotal role in human health. Increasing numbers of studies suggest that the gut microbiota can influence the brain and behavior of patients. Various metabolites secreted by the gut microbiota can affect the cognitive ability of patients diagnosed with neurodegenerative diseases.

Objective: To determine the value of galactomannan (GM) in bronchoalveolar lavage fluid (BALF) for diagnosing invasive pulmonary aspergillosis.

Methods: According to the European Organization for Research and Treatment of Cancer / Invasive Fungal Infection Group (EORTC / IFICG) and the American Mycosis Research Group (MSG),and the American College of Infectious Diseases (IDSA) guidelines,295 patients with pulmonary aspergillosis (IPA) and high risk of invasive infections were divided into four groups: IPA group (42 cases),clinically diagnosed group (68 cases),suspected group (61 cases),and non-IPA group (124 cases). Their serum and BALF concentrations of GM were detected by enzyme-linked immunosorbent assay (ELISA).

Objective: To evaluate the effects of environmental factors and microRNAs (miRNAs) (miR-126, miR-143, and miR-145) on the risk of coronary heart disease (CHD).

Methods: A frequency-matched case-control study (450 patients, 450 controls) was conducted from April 2014 to December 2016 in Fuzhou City, China. Environmental factors were investigated using a self-administered questionnaire, and the expression levels of miR-126, miR-143, and miR-145 were determined by quantitative real-time Polymerase Chain Reaction (PCR) in peripheral blood mononuclear cells.

The aim of this study was to investigate the bacteriostatic and bactericidal effects of diminazene aceturate (DA) against five strains of pathogenic bacteria and two strains of nonpathogenic bacteria. The results showed that 5 μg/mL of DA suppressed the growth of pathogenic by as much as 77% compared with the controls. Enterohemorrhagic EDL933 (an O157:H7 strain) was the most sensitive to DA with a minimum inhibitory concentration of 20 μg/mL.
