Primary Sjögren's syndrome (pSS) is an autoimmune inflammatory disorder characterized by lymphocytic infiltration of exocrine glands, mainly the lacrimal and salivary glands leading to a chronic sicca syndrome. However, extraglandular organ systems may frequently be involved, including both central and peripheral nervous systems. ⋯ The spectrum of pSS-related neuropathies is wide including sensory neuropathies, neuronopathies, sensory-motor neuropathies, mononeuritis multiplex related to vasculitis… Central nervous system involvement is composed by multiple sclerosis-like manifestations including acute and chronic myelopathies and by more diffuse manifestations (cognitive dysfunction, subacute aseptic meningitis, encephalopathy, psychiatric symptoms, chorea, seizures…). The diagnosis and treatment of such pSS-related manifestations must be optimized in order to avoid severe disability.

An increasing body of research demonstrates that homelessness is an independent risk factor for morbidity and premature death. This paper compares the frequency of diagnoses between 2003 and 2009 in the computerised records of a specialist practice for homeless people. The changing morbidity trends revealed offer a basis for comparison with other services and suggest benefits from collaborative working, particularly around substance misuse and mental health.

To determine whether fear avoidance beliefs (FABs) in older adults with chronic low back pain (CLBP) are significantly associated with gait speed decline and/or self-report of greater disability. ⋯ FABs related to physical activity in older adults with CLBP were significantly associated with both self-reported and performance-based disability after controlling for known confounders. Previous studies have reported similar associations between self-reported measures of disabling back pain and FABs. Ours is the first study to examine the relationship between FAB and gait speed, a powerful predictor of morbidity and mortality. Future work should examine whether targeting fear avoidance in addition to other psychosocial measures in older adults with CLBP improves gait speed and functional independence.

In contrast to mammals, adult teleost fish exhibit an enormous potential to regenerate neuronal tissue after injuries to the CNS. By combining a well-defined cerebellar lesion paradigm with differential proteome analysis at a post-lesion survival time of 3 days, we screened for protein candidates involved in repair of the fish brain. ⋯ The cellular localization and the spatiotemporal patterns of two of these proteins, beta-actin and beta-tubulin, were further characterized through immunohistochemistry. Comparison of the observed changes in protein abundance with the previously characterized events underlying regeneration of the cerebellum suggests that the proteins identified are especially involved in cellular proliferation and survival, as well as axonal sprouting.
