Implementing Advance Care Planning and Care Coordination in the Care for People With Parkinson Disease: A Feasibility Study.

BACKGROUND: For people with a moderate stage of Parkinson disease (PD), dedicated care coordination combined with advance care planning (ACP) is highly needed. However, evidence is lacking. The objective of this study was to assess the feasibility and acceptability of the study processes to inform a larger randomized controlled trial, aiming the effectiveness of a combined intervention on ACP and care coordination for people with PD.

Small molecule 1a reduces FMRpolyG-mediated toxicity in in vitro and in vivo models for FMR1 premutation.

Fragile X-associated tremor and ataxia syndrome (FXTAS) is a late-onset, progressive neurodegenerative disorder characterized by tremors, ataxia and neuropsychological problems. This disease is quite common in the general population with approximately 20 million carriers worldwide. The risk of developing FXTAS increases dramatically with age, with about 45% of male carriers over the age of 50 being affected.

Neuropathology of -premutation carriers presenting with dementia and neuropsychiatric symptoms.

CGG repeat expansions within the premutation range (55-200) of the gene can lead to Fragile X-associated tremor/ataxia syndrome and Fragile X-associated neuropsychiatric disorders. These CGG repeats are translated into a toxic polyglycine-containing protein, FMRpolyG. Pathology of Fragile X-associated tremor/ataxia syndrome and Fragile X-associated neuropsychiatric disorders comprises FMRpolyG- and p62-positive intranuclear inclusions.

Short antisense oligonucleotides alleviate the pleiotropic toxicity of RNA harboring expanded CGG repeats.

Fragile X-associated tremor/ataxia syndrome (FXTAS) is an incurable neurodegenerative disorder caused by expansion of CGG repeats in the FMR1 5'UTR. The RNA containing expanded CGG repeats (rCGG) causes cell damage by interaction with complementary DNA, forming R-loop structures, sequestration of nuclear proteins involved in RNA metabolism and initiation of translation of polyglycine-containing protein (FMRpolyG), which forms nuclear insoluble inclusions. Here we show the therapeutic potential of short antisense oligonucleotide steric blockers (ASOs) targeting directly the rCGG.
