Association of obesity with mild traumatic brain injury symptoms, inflammatory profile, quality of life and functional outcomes: a TRACK-TBI Study.
Obesity is associated with chronic inflammation, which may impact recovery from mild traumatic brain injury (mTBI). The objective was to assess the role of obesity in recovery of symptoms, functional outcome and inflammatory blood biomarkers after mTBI. ⋯ Obesity is associated with higher symptomatology at 6 and 12 months and higher concentrations of blood inflammatory markers throughout recovery following mTBI.

Prognostic significance of peripheral neutrophils and lymphocytes in early untreated Parkinson's disease: an 8-year follow-up study.
To explore whether peripheral blood neutrophils and lymphocytes are associated with longitudinal motor and cognitive decline in patients with early Parkinson's disease (PD) and, to uncover the disease-specific mechanisms underlying these associations. ⋯ Among the blood biomarkers, only a higher neutrophil count was associated with faster motor progression along with accelerated nigrostriatal dopaminergic degeneration in patients with PD. The impact of neutrophils and lymphocytes on longitudinal cognitive changes remains unclear.

Pathogenic role of anti-cN1A autoantibodies in sporadic inclusion body myositis.
Sporadic inclusion body myositis (sIBM) is an intractable muscle disease that frequently affects elderly people. Autoantibodies recognising cytosolic 5'-nucleotidase 1A (cN1A) were found in the sera of patients with sIBM. However, the pathogenic role of the autoantibodies remained unknown. This study investigated the pathogenic properties of the autoantibodies using active cN1A peptides immunisation. ⋯ Active cN1A peptide immunisation partially reproduced the clinical and histological aspects of sIBM in wild-type mice. The murine model demonstrates the pathogenic properties of anti-cN1A autoantibodies to cause sIBM-like histological changes.
