Oronasal mucosal melanoma is defined by two transcriptional subtypes in humans and dogs with implications for diagnosis and therapy.

Mucosal melanoma is a rare melanoma subtype associated with a poor prognosis and limited existing therapeutic interventions, in part due to a lack of actionable targets and translational animal models for preclinical trials. Comprehensive data on this tumour type are scarce, and existing data often overlooks the importance of the anatomical site of origin. We evaluated human and canine oronasal mucosal melanoma (OMM) to determine whether the common canine disease could inform the rare human equivalent.

Understanding the determinants and outcomes of education in pulmonary rehabilitation: moving towards person-centered care.

Topic Importance: Education and psychosocial support are essential components of pulmonary rehabilitation (PR). However, the delivery of education often follows a one-size-fits-all approach, with individual factors that influence learning rarely considered. Moreover, education-related outcomes are frequently overlooked in PR assessments, and inconsistent use of these outcomes has limited our understanding of the impact of education on people with chronic respiratory diseases.

Impulse control disorders in Parkinson's disease: What's new?

Impulse Control Disorders (ICDs) are increasingly recognized as a significant non-motor complication in Parkinson's disease (PD), impacting patients and their caregivers. ICDs in PD are primarily associated with dopaminergic treatments, particularly dopamine agonists, though not all patients develop these disorders, indicating a role for genetic and other clinical factors. Studies over the past few years suggest that the mesocorticolimbic reward system, a core neural substrate for impulsivity, is a key contributor to ICDs in PD.

Dysregulated autoantibodies targeting AGTR1 are associated with the accumulation of COVID-19 symptoms.

Coronavirus disease 2019 (COVID-19) presents a wide spectrum of symptoms, the causes of which remain poorly understood. This study explored the associations between autoantibodies (AABs), particularly those targeting G protein-coupled receptors (GPCRs) and renin‒angiotensin system (RAS) molecules, and the clinical manifestations of COVID-19. Using a cross-sectional analysis of 244 individuals, we applied multivariate analysis of variance, principal component analysis, and multinomial regression to examine the relationships between AAB levels and key symptoms.
