Intestinal parasitic infections can cause significant morbidity and mortality in individuals with cancer. Despite this, they are often self-limiting in healthy individuals. is an anaerobic parasite that causes amebiasis in infected individuals. Poor sanitary conditions and endemic areas increase the risk of contracting amebiasis. Furthermore, giardiasis is a parasitic infection of the small intestine that is caused by , a flagellated protozoan. In both cases, the disease burden is greater and the timeline is longer among immunosuppressed patients. Due to this, we aimed to more thoroughly characterize disease progression and treatment efficacy of these intestinal parasitic infections in cancer patients by presenting a case of intestinal amebiasis and enterocolitis due to as well as two giardiasis cases, while also providing a review of the literature.

Purpose Of Review: Diagnostic stewardship (DS) aims to optimise the use of laboratory testing to improve patient care while reducing unnecessary tests. This review examines recent evidence on DS interventions to optimise the use of resources, focusing on three key areas: reducing unnecessary testing, maximising the impact of existing tests, and avoiding the overdiagnosis of hospital-acquired infections.
Recent Findings: Multiple interventions have demonstrated effectiveness in reducing unnecessary blood and urine culture testing, including clinical decision support tools, education programs, and multidisciplinary approaches.

Purpose Of Review: Plasma metagenomic next-generation sequencing (mNGS) enables detection of microbial cell-free deoxyribonucleic acid (mcfDNA) in blood without the need for culture or organism-specific primers. Here, we review clinical performance, methodological variability, and real-world application of plasma mNGS for infectious disease diagnosis in immunocompromised hosts (ICHs).
Recent Findings: Plasma mNGS has rapidly gained attention as a novel diagnostic tool for infections in ICHs, offering broad-range pathogen detection from a noninvasive blood sample.

Thyroid cancer, a prevalent endocrine malignancy, is influenced by its tumor microenvironment (TME), with cancer-associated fibroblasts (CAFs) playing a pivotal role in disease progression. Molecularly, CAFs orchestrate a pro-tumorigenic niche via cytokine secretion and extracellular matrix (ECM) stiffening, underscoring their targetability. Therapeutic strategies, including small molecule inhibitor-based therapies, immune-based therapies, nanoparticle-based approaches, and combination regimens, have been evaluated for their efficacy in disrupting CAF functionality.

The systematic identification of human-virus protein-protein interactions (PPIs) is a critical step toward elucidating the underlying mechanisms of viral infection, directly informing the development of targeted interventions against existing and emerging viral threats. In this work, we presented DeepGNHV, an end-to-end framework that integrated a pretrained protein language model with structural features derived from AlphaFold2 and leveraged graph attention networks to predict human-virus PPIs. In comparison to other state-of-the-art approaches, DeepGNHV exhibited superior predictive performance, especially when applied to viral proteins absent from the training process, indicating its strong generalization capability for detecting newly emerging virus-related PPIs.

Outer membrane vesicles (OMVs) are nanosized vesicles naturally secreted by Gram-negative bacteria and represent a promising platform for vaccine development. OMVs possess inherent immunostimulatory properties due to the presence of pathogen-associated molecular patterns (PAMPs), providing self-adjuvanting capabilities and the ability to elicit both innate and adaptive immune responses. This review outlines the advantages of OMVs over traditional vaccine strategies, including their safety, modularity, and the potential for genetic engineering to enable targeted antigen delivery.
