Review Meta AnalysisParkinson's disease and risk of mortality: meta-analysis and systematic review.
To evaluate the existing prospective observational studies on the morality risk among Parkinson's disease (PD) patients and determine the overall risk ratio (RR) of mortality by conducting a meta-analysis and systematic review. Original articles published in English were searched in PubMed and Embase databases prior to March 2013. Only prospective observational studies providing adjusted risk estimates related to PD and future mortality were considered eligible. ⋯ PD patients with dementia had particularly high mortality risks (RR = 3.78; 95% CI: 2.06-6.92). This meta-analysis indicated that among patients with PD, the all-cause mortality increased by 2.22-fold compared with the general population. PD patients with dementia particularly had higher risks of mortality.

Randomized Controlled Trial Comparative StudyEquivalency of tricyclic antidepressants in open-label neuropathic pain study.
To compare adverse effects, tolerability and efficacy of the tricyclic antidepressants (TCAs) amitriptyline and nortriptyline in management of neuropathic pain due to peripheral neuropathy (PN). ⋯ Amitriptyline and nortriptyline are equivalent for overall adverse effects and discontinuation rates. Either TCA should be equally considered for use in neuropathic pain due to PN. When used as monotherapy or as part of adjuvant therapy, either TCA can be expected to provide approximately 23-26% visual analog scale pain reduction if tolerated. Discontinuations due to inefficacy or adverse effects can be anticipated in 26-37% of patients initiated on either TCA for PN-associated neuropathic pain.

Higher levels of reported sun exposure, and not vitamin D status, are associated with less depressive symptoms and fatigue in multiple sclerosis.
Insufficient sun exposure and vitamin D deficiency have both been associated with increased risk of multiple sclerosis (MS). Depressi on, anxiety, fatigue and cognitive impairment are prevalent and disabling symptoms in MS. Our objective was to examine the associations between personal sun exposure and serum 25-hydroxyvitamin D (25(OH)D), and depression, anxiety, fatigue and cognition. ⋯ We found that higher levels reported sun exposure, rather than 25(OH)D levels, were associated with less depressive symptoms and levels of fatigue. The role of UV or light therapy will need to be evaluated in randomized controlled trials to confirm an effect on these symptoms in MS.
