Sjögren's syndrome is a multisystem inflammatory rheumatic disease that is classified into primary and secondary forms, with cardinal features in the eye (keratoconjunctivitis sicca) and mouth (xerostomia). The aetiology behind this autoimmune exocrinopathy is probably multifactorial and influenced by genetic as well as by environmental factors that are as yet unknown. A genetic predisposition to Sjögren's syndrome has been suggested on the basis of familial aggregation, animal models and candidate gene association studies. Recent advances in molecular and genetic methodologies should further our understanding of this complex disease. The present review synthesizes the current state of genetics in Sjögren's syndrome.

Polycystic ovary syndrome (PCOS), a complex heterogenic disease of unknown etiology, is the most common endocrine disorder in women of reproductive age. Sufferers often exhibit significant insulin resistance, glucose intolerance, obesity, and dyslipidemia. There is no cure for PCOS, although metformin and weight reduction have shown some benefits.

Fibromyalgia is a syndrome characterised by persistent unexplained pain and fatigue. People with fibromyalgia report receiving little support to manage symptoms, difficult interactions with healthcare practitioners and stigma associated with this contested condition. In this article, we employ Dorothy E Smith's Sociology for People to undertake a systems-focused literature review from the standpoint of people with fibromyalgia, moving beyond individual subjectivities to map how problems are socially organised.

Context: COVID-19 has been associated with features of a cytokine storm syndrome with some patients sharing features with the hyperinflammatory disorder, secondary hemophagocytic lymphohistiocytosis (sHLH).
Hypothesis: We hypothesized that proteins associated with sHLH from other causes will be associated with COVID-sHLH and that subjects with fatal COVID-sHLH would have defects in immune-related pathways.
Methods And Models: We identified two cohorts of adult patients presenting with COVID-19 at two tertiary care hospitals in Seattle, Washington in 2020 and 2021.

Lewy body (LB) pathology is present as a co-pathology in approximately 50% of Alzheimer's disease (AD) dementia patients and may even represent the main neuropathologic substrate in a subset of patients with amnestic impairments. However, the degree to which LB pathology affects the neurodegenerative course and clinical phenotype in amnestic patients is not well understood. Recently developed α-synuclein seed amplification assays (αSyn-SAAs) provide a unique opportunity for further investigating the complex interplay between AD and LB pathology in shaping heterogeneous regional neurodegeneration patterns and clinical trajectories among amnestic patients.
