Abstract

fetched live from OpenAlex

Introduction:We aimed to describe the epidemiological, clinical, laboratory characteristics, and outcomes of central nervous system (CNS) mycosis in patients with human immunodeficiency virus (HIV) and to determine characteristics associated with a higher risk of death.Retrospective data from 77 case histories of HIV-infected patients with neurological symptoms caused by various fungi including Candida and Cryptococcus in Dnipro, Ukraine, were analysed as a case-control study with 40 deceased individuals considered as cases and 37 patients with favourable outcome (survivors) considered as controls.Material and methods: Fungi in cerebrospinal fluid (CSF) were detected with traditional culture methods.Multivariate analysis used (1) binary logistic regression with survivor/dead as a dependent variable and (2) a classification and regression tree (CRT method).Results: A combination of fungal infection with other infections of CNS (dual and triple coinfection) was diagnosed in most cases (n = 53, 68.8%), while the proportion of co-infection was somewhat lower among survivors (59.5%).Clinical manifestations were non-specific.Risk of death was higher among those with tuberculosis (AOR = 2.7, 95% CI: 1.0-7.5)and lower among those infected with Epstein-Barr virus (EBV) (AOR = 0.3, 95% CI: 0.1-1.0)and among patients on ART (AOR = 0.2, 95% CI: 0.1-0.8).Risk of death significantly decreased over time.The classification tree shows that among HIV-mycosis neurological patients not on ART with tuberculosis, the risk of death constituted 75%, while among patients on ART with EBV-infection, all patients survived.Conclusions: Opportunistic mycoses remain an important clinical challenge among immuno-compromised patients especially those who were diagnosed with HIV late, failed to get antiretroviral therapy, and developed tuberculosis.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
