Breast cancer is the leading cause of cancer-related deaths among women worldwide. Early detection through mammography significantly improves outcomes, with breast density acting as both a risk factor and a key interpretive feature. Although the Breast Imaging Reporting and Data System (BI-RADS) provides standardized density categories, assessments are often subjective and variable.

Lichen simplex chronicus (LSC), also known as neurodermatitis, is a common chronic pruritic dermatosis defined by lichenified plaques resulting from persistent scratching. Though often secondary to underlying dermatologic, systemic, or psychological triggers, LSC represents a distinct clinical entity with significant morbidity. The hallmark itch-scratch cycle contributes not only to visible skin changes but also to substantial sleep disruption, emotional distress, and functional impairment.

The indirect immunofluorescence assay (IFA) on HEp-2 cells is the prevailing method used to screen for autoantibodies in the investigation of systemic autoimmune diseases (SAID). When positive, the titer provides a semi-quantitative assessment of the autoantibody serum concentration whereas the immunofluorescence pattern indicates the possible autoantibody specificities. The Brazilian Consensus on ANA Patterns (BCA) and the International Consensus on ANA Patterns (ICAP) provide recommendations for the harmonization on the pattern nomenclature and test reporting.

Chronic urticaria (CU) is a skin disease characterized by recurrent episodes of urticaria and/or angioedema, persisting for more than six weeks. Chronic urticaria is classified as chronic spontaneous urticaria (CSU) and chronic inducible urticaria (CIndU). Histamine, released by mast cells and basophils, is the central mediator in the development of signs and symptoms, especially pruritus.

The 2019 pandemic of coronavirus disease (COVID-19) caused by SARS-CoV-2 led to millions of deaths worldwide since its emergence. The viral genomic material can code structural and non-structural proteins including the main protease or 3CL, a cysteine protease that cleavages the viral polyprotein generating 11 proteins that participate in viral pre-replication. Thus, 3CL is a promising therapeutic target for SARS-CoV-2 inhibition by new drugs or drug repositioning because 3CL is dissimilar to human proteases.

Atypical hemolytic uremic syndrome (aHUS) is a rare cause of thrombotic microangiopathy (TMA) caused by the dysregulation of the alternative complement pathway. The diagnosis of TMA is made clinically by the triad: microangiopathic hemolytic anemia, thrombocytopenia, and organ damage (mainly acute kidney injury). The heterogeneity of clinical manifestation and the lack of a gold standard diagnostic test makes the precise diagnosis of aHUS a challenging process that may impact patient management.

Recent advances in genomic methodologies have significantly enhanced our understanding of immune-mediated rheumatic diseases. Specific structural variants (SVs), such as substantial DNA deletions or insertions, including chromosomal aberrations, have been implicated in diseases of immune dysregulation. Regrettably, SVs are frequently overlooked in next-generation sequencing (NGS) targeted-gene panels, whole exome sequencing (WES) and whole genome sequencing (WGS).

External quality assurance (EQA) programs play a pivotal role in monitoring laboratory practices, allowing each laboratory to evaluate the consistency of results across different methods as well the ability of individual laboratories to compare and improve over time their own performance. The objective of our study was to analyze the UK NEQAS EQA reports for the "Antibodies to Nuclear and Related Antigens" program from 2013 to 2023, to assess the overall level of harmonization of the responses for anti-nuclear antibody (ANA) testing by indirect immunofluorescence (IIF), in terms of both pattern and titer consensus. As a second aim, we analyzed the impact of the introduction in UK NEQAS EQA reports of the International Consensus on ANA Patterns (ICAP) nomenclature and of digital image recognition on the harmonization of the ANA HEp-2 IIF test.

Article Synopsis
  • MOGAD encephalitis and ADEM present similar symptoms to autoimmune encephalitis (AE) linked with anti-neuronal antibodies, but their treatment and outcomes vary, and testing for anti-MOG antibodies is not routine.
  • In a study of 481 patients with suspected AE, only 3.5% had anti-MOG antibodies, with a higher prevalence in children compared to adults.
  • Patients with MOGAD exhibited fewer behavioral and movement disorders compared to those with AE, but had more symptoms related to demyelination, highlighting the need to consider MOGAD as a differential diagnosis in cases of possible AE.

Objective: To analyze in silico the evidence of molecular mimicry between human beta-cell autoantigens and cow's milk proteins as a potential type 1 diabetes mellitus (T1DM) trigger.

Materials And Methods: The in silico analysis was performed using bioinformatics tools to compare the amino acid sequences of cow's milk proteins (bovine serum albumin [BSA] and beta-lactoglobulin [BLG]) and human beta-cell autoantigens (glutamic acid decarboxylase-65 [GAD-65], insulin, and zinc transporter 8 [ZnT8]). The structural and functional characteristics of the proteins were analyzed to identify potential molecular mimicry mechanisms.

Angiosperms are the most dominant land plant flora and have colonized most of the terrestrial habitats, thriving in different environmental conditions, among which light and temperature play a crucial role. In the eudicot Arabidopsis thaliana, light and temperature are integrated into a phytochrome B (phyB)-dependent signalling network that regulates development. However, whether this signal integration controls the development in other angiosperm lineages and whether phyB is a conserved hub of this integratory network in angiosperms is unclear.
