Artificial intelligence-based tools designed to assist in the diagnosis of lymphoid neoplasms remain limited. The development of such tools can add value as a diagnostic aid in the evaluation of tissue samples involved by lymphoma. A common diagnostic question is the determination of chronic lymphocytic leukemia (CLL) progression to accelerated CLL (aCLL) or transformation to diffuse large B-cell lymphoma (Richter transformation; RT) in patients who develop progressive disease. The morphologic assessment of CLL, aCLL, and RT can be diagnostically challenging. Using established diagnostic criteria of CLL progression/transformation, we designed four artificial intelligence-constructed biomarkers based on cytologic (nuclear size and nuclear intensity) and architectural (cellular density and cell to nearest-neighbor distance) features. We analyzed the predictive value of implementing these biomarkers individually and then in an iterative sequential manner to distinguish tissue samples with CLL, aCLL, and RT. Our model, based on these four morphologic biomarker attributes, achieved a robust analytic accuracy. This study suggests that biomarkers identified using artificial intelligence-based tools can be used to assist in the diagnostic evaluation of tissue samples from patients with CLL who develop aggressive disease features. © 2021 The Pathological Society of Great Britain and Ireland.

Unlabelled: Forming wound canal is one of the main signs of gunshot wound. Its features are related to the following differential diagnostic signs: presence of gunshot wound, its intravitality, prescription, direction of projectile (bullet) movement, power of used weapon, etc.
Objective: To study the mechanisms of wound canal formation in gunshot injury, the pattern of damage to the biological tissues of its walls (mainly, blood vessels), the features of hemorrhages forming around it.

Objective: To analyze the filum terminale (FT) of children with tethered cord syndrome (TCS) and aborted fetuses without neurological disorders in order to investigate the expression of significantly differentially expressed proteins in the FT under both pathological and physiological conditions.
Methods: According to the inclusion and exclusion criteria, 35 FT samples were selected, and the samples were subjected to immunohistochemistry and H&E staining. The data were analyzed using one-way analysis of variance, and P < 0.

Immunogenic cell death (ICD) is a type of cell death sparking adaptive immune responses that can reshape the tumor microenvironment. Exploring key ICD-related genes in bladder cancer (BLCA) could enhance personalized treatment. The Cancer Genome Atlas (TCGA) BLCA patients were divided into two ICD subtypes: ICD-high and ICD-low.

Unlabelled: (SA) colonizes most mammals but also represents a danger in clinical settings because it evolves resistance against antibiotics, and SA infections represent a leading cause of death worldwide. SA nasal carriage provides the bacterial reservoir for opportunistic infection because clinical strains often match the patient's own nasally carried strain. The global SA carriage rate is typically reported as 25%-30% after sampling subjects once or twice and defining carrier status using culture-based methods.

Aims: Sarcoid myopathy (SaM) is characterised by granulomatous myositis (GM) and can overlap with inclusion body myositis (IBM), a late-onset chronic idiopathic inflammatory myopathy with a still enigmatic pathogenesis. As GM can occur in different clinical contexts, we aimed to examine the histomorphologic features and gene expression profiles in cases of definite SaM that may inform diagnostic and therapeutic considerations.
Methods: We performed a multidimensional characterisation of muscle biopsy specimens from patients with 'pure SaM' (n=17), SaM with concomitant IBM (SaM-IBM) (n=2), including histopathologic and ultrastructural analysis in addition to quantitative real-time polymerase chain reaction.
