Association between aluminum in drinking water and incident Alzheimer's disease in the Canadian Study of Health and Aging cohort.
Abstract Epidemiological evidence linking aluminum in drinking water and Alzheimer's disease (AD) has been inconsistent, with previous studies often limited by small sample sizes. The present study addresses this issue using data from the Canadian Study of Health and Aging (CSHA), a prospective cohort of 10,263 subjects followed-up from 1991-1992 through 2001-2002. Participants' residential histories were linked to municipal drinking water sources in 35 Canadian municipalities to obtain ecologic pH, aluminum, fluoride, iron and silica concentrations in drinking water. Cox proportional hazards models were used to e...

How to Keep Alzheimer ’s From Bringing About the Zombie Apocalypse
I tried to kill my father for years. To be fair, I was following his wishes. He’d made it clear that when he no longer recognized me, when he could no longer talk, when the nurses started treating him like a toddler, he didn’t want to live any longer. My father was 58 years old when he was diagnosed with Alzheimer’s disease. He took the diagnosis with the self-deprecating humor he’d spent a lifetime cultivating, constantly cracking jokes about how he would one day turn into a zombie, a walking corpse. We had a good 10 years with him after the diagnosis. Eventually, his jokes came true. Seven years ...

Reduction of Leukocyte Microvascular Adherence and Preservation of Blood-Brain Barrier Function by Superoxide-Lowering Therapies in a Piglet Model of Neonatal Asphyxia
Conclusion: Using three different strategies to either prevent formation or enhance elimination of O2⋅_ during the post-asphyxial period, we saw both reduced leukocyte adherence and preserved BBB function with treatment. These findings suggest that agents which lower O2⋅_ in brain may be attractive new therapeutic interventions for the protection of the neonatal brain following asphyxia. Introduction Asphyxia is a relatively common source of neonatal brain damage (1), affecting ~2 in every 1,000 births (2). The hypoxic ischemia resulting from this oxygen deprivation can produ...

Associations of Anemia With Outcomes in Patients With Spontaneous Intracerebral Hemorrhage: A Meta-Analysis
Conclusions: Anemia on admission was associated with higher mortality and an increased risk of poor outcome in patients with ICH. However, the results were limited by the high heterogeneity of included studies. Prospective, multi-center or population-based, large sample cohort studies are needed in the future. Introduction Intracerebral hemorrhage (ICH) is the second most common cause of stroke and a highly lethal disease (1), which still lacks effective therapeutic interventions (2, 3). Although age, baseline ICH volume and neurological status on admission are well-known predictors of outcome of ICH (4), none of t...

Phagocytosis in the Brain: Homeostasis and Disease
Conclusions and Perspectives In this review we have summarized the critical role phagocytosis plays in both CNS homeostasis and disease. While much progress has been made in recent years, many unanswered questions remain. How phagocytosis in the CNS is influenced by numerous factors, such as microenvironment or phagocytic target, have yet to be fully resolved. Additionally, the utilization of novel technologies, including in vivo imaging techniques (217), iPSC-derived microglia (213) and high-throughput screens (66), will likely contribute to further identification of phagocytic pathways and consequences of phagocytosis w...

Functional MRI of Letter Cancellation Task Performance in Older Adults
Conclusion The present work is the first to identify neural correlates of the LCT using fMRI and tablet technology in a healthy aging population. Across all ages, the activation was found to be bilateral, including in the cerebellum, superior temporal lobe, precentral gyrus, frontal gyrus, and various occipital and parietal areas. With increasing age, performance generally decreased and brain activity was reduced in the supplementary motor area, middle and inferior frontal gyrus, middle occipital gyrus, putamen and cerebellum. Better LCT performance was correlated with increased activity in the middle frontal gyrus, and r...

Characterizing the Penumbras of White Matter Hyperintensities and Their Associations With Cognitive Function in Patients With Subcortical Vascular Mild Cognitive Impairment
Conclusion In this study, reduced CBF and FA and increased MD in the inner NAWM layers for both PVWMH and DWMH suggested extensive WM alterations beyond the visible WM lesions commonly observed on clinical MRI of svMCI subjects. CBF penumbras cover more extensive WM at risk than DTI penumbras, suggesting the likelihood that compromised CBF precedes white matter integrity changes, and CBF penumbras may be a potential target for the prevention of further microstructural white matter damage. The imaging parameters investigated, however, did not correlate to cognition. Author Contributions YZ, QX, and XG conceived and desig...

Collectivism Is Associated With Greater Neurocognitive Fluency in Older Adults
This study aimed to evaluate the impact of self-construal on neurocognitive functions in older adults. A total of 86 community-dwelling older adults 60 years and older were assessed with three common self-report measures of self-construal along individualism and collectivism (IC). A cognitive battery was administered to assess verbal and non-verbal fluency abilities. Latent profile analysis (LPA) was used to categorize individuals according to IC, and one-way analyses of covariance (ANCOVA), including relevant covariates (e.g., ethnicity, gender, linguistic abilities), were used to compare neurocognitive functions between ...

Carbon pricing: a win-win environmental and public health policy.
Abstract Carbon pricing is an important tool for mitigating climate change. Carbon pricing can have significant health co-benefits. Air pollution from fossil fuels leads to detrimental health effects, including premature mortality, heart attacks, hospitalization from cardiorespiratory conditions, stroke, asthma exacerbations, and absenteeism from school and work, and may also be linked to autism spectrum disorder and Alzheimer's disease. Reduction in fossil fuel combustion through a carbon price can lead to improvements in all these areas of health. It can also improve health by encouraging active transportation c...
