Review Meta Analysis
Onset and progression factors in Parkinson's disease: A systematic review.
Current research has identified several factors thought to be associated with the onset and progression of Parkinson's Disease (PD); however, whether certain factors contribute to or are protective against PD remains unclear. As such, a systematic search of the literature was performed using variations of MeSH and keyword search terms to identify and summarize systematic reviews and primary studies pertaining to factors associated with the onset and progression of PD. Factors referred to both traditional risk factors and prodromal markers. ⋯ Conversely, coffee consumption, cigarette smoking, and some polymorphisms were consistently found to be negatively associated with the onset of PD. Urate was the only identified factor linked to the progression of PD; it was mostly found to be negatively associated with PD. In sum, the evidence was systematically found and summarized in the literature pertaining to factors related to the onset and progression of PD.

Review Meta Analysis
Factors associated with the onset and progression of neurotrauma: A systematic review of systematic reviews and meta-analyses.
Neurotrauma, including traumatic brain injury (TBI) and spinal cord injury (SCI), is a preventable condition that imposes an important burden on the Canadian society. In this study, the current evidence on risk factors for the onset and progression of neurotrauma is systematically reviewed and synthesized. Searches of the Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects (DARE), Medline and Medline in Process (via OVID), EMBASE and PsycINFO from inception to February 2013 were conducted to identify relevant systematic reviews and meta-analyses published in English or French. ⋯ Substantial evidence supports the use of helmets for the prevention of TBI in sports and motorcycling and face shields in ice hockey. Addressing bicycle helmet legislation across Canada may be an effective option for reducing TBI caused by bicycle accidents. Limited evidence on relevant risk factors for spinal cord injuries and neurotrauma progression was available.
