BACKGROUND SARS-CoV-2 infection can persist in immunocompromised patients with hematological malignancies, despite antiviral treatment. This report is of a 67-year-old man with chronic lymphocytic leukemia (CLL), secondary hypogammaglobulinemia, and thrombocytopenia on maintenance therapy with ibrutinib, with persistent SARS-CoV-2 infection unresponsive to antiviral treatment, including remdesivir, nirmatrelvir/ritonavir (Paxlovid), and tixagevimab/cilgavimab (Evusheld). CASE REPORT The patient was admitted to our hospital 3 times.

The diagnosis of bloodstream infection (BSI) may rely on a PCR-based analysis of a positive blood culture (PBC) obtained from the patient at the time of BSI. In this study, a yeast DNA extraction protocol for use on PBCs was developed and evaluated with the molecular mouse (MM) yeast blood (YBL) chip-based PCR assay, which allowed us to detect nine medically relevant species. We studied 125 simulated or clinical PBCs for species.

The ongoing epidemic of mpox, namely human monkeypox virus (MPXV) infection, requires rapid and reliable laboratory diagnosis. We report on the QIAstat-Dx viral vesicular panel PCR assay that allows the detection of (within 75 min) six vesicular disease-causing viruses, including MPXV. We analyzed 168 clinical samples, known to be positive (51 samples) or negative (117 samples) for MPXV clade II, obtained from patients at their mpox diagnosis or follow-up.

Thyroid cancer is the most prevalent endocrine malignancy and comprises a wide range of lesions subdivided into differentiated (DTC) and undifferentiated thyroid cancer (UTC), mainly represented by the anaplastic thyroid carcinoma (ATC). This is one of the most lethal malignancies in humankind leading invariably to patient death in few months. Then, a better comprehension of the mechanisms underlying the development of ATC is required to set up new therapeutic approaches.

Article Synopsis
  • Candida auris and other Candida species are significant causes of bloodstream infections, requiring prompt antifungal treatment; however, the presence of antifungal agents can hinder the effectiveness of blood cultures used for diagnosis and monitoring.
  • A study compared different blood culture media to determine their effectiveness in identifying Candida species in the presence of high concentrations of antifungal drugs; findings showed that certain media (FAP and PAF) were better at fostering the growth of C. auris and C. glabrata even with antifungal presence.
  • The research highlights challenges in treating bloodstream infections from resistant Candida species, primarily C. auris and C. glabrata, especially when using echinocandins
