Where You Live Can Shape How Alzheimer ’ s Affects You
The FDA in mid-July for the first time ever approved an Alzheimer’s drug, Leqembi. The annual price-tag will run patients $26,500. The same week, the Alzheimer’s Association for the first time ever released county-level data to identify which communities are most struggling with the disease. 6.7 million Americans live with Alzheimer’s disease and 134,000 of them will die because of it each year. We’ve known these aggregate numbers for a while now, but with new data and new drugs, healthcare specialists can now better target attention and resources. [time-brightcove not-tgx=”true”] ...

Extreme Heat Is Endangering America ’ s Workers —And Its Economy
This project was supported by the Pulitzer Center 7 A.M.: COPELAND FARMS—ROCHELLE, GA Just after dawn on a recent July day in Rochelle, Ga., Silvia Moreno Ayala steps into a pair of sturdy work pants, slips on a long-sleeved shirt, and slathers her face and hands with sunscreen. She drapes a flowered scarf over her wide-brimmed hat to protect her neck and back from the punishing rays of the sun. There isn’t much she can do about the humidity, however. Morning is supposed to be the coolest part of the day, but sweat is already pooling in her rubber boots. [time-brightcove not-tgx=”true”] ...

Impaired Activity of Ryanodine Receptors Contributes to Calcium Mishandling in Cardiomyocytes of Metabolic Syndrome Rats
Conclusion Principal findings of this work are that abnormal Ca2+ transient amplitude, contractile dysfunction; and impaired relaxation of MetS cardiomyocytes underlies intrinsic dysfunctional RyR2 and SERCA pump. Abnormal activity of RyRs was evidenced by its decreased ability to bind [3H]-ryanodine. Although the MetS condition does not modify RyR2 protein expression, its phosphorylation at Ser2814 is decreased, which impairs its capacity for activation during ECC. The dysfunctional RyRs, together with a decreased activity of SERCA pump due to decreased Thr17-PLN phosphorylation suggest a downregulation of CaMKII in MetS...

Harnessing the Four Elements for Mental Health
DiscussionAs detailed above, the “elements” in both a classical and a contemporary sense have effects on our mental health and are potentially modifiable aspects that can be harnessed as therapeutic interventions. The most robust interventional evidence currently available shows tentative support for several use of the elements via horticultural and nature-exposure therapy, green exercise/physical activity, sauna and heat therapy, balneotherapy, and breathing exercises. It should be noted that, in many cases, these interventions were not studied in definitive diagnosed psychiatric disorders and thus it is pre...

Influence of Sex on Stroke Prognosis: A Demographic, Clinical, and Molecular Analysis
Conclusion Our data suggest that women who suffer from IS present with a poorer functional outcome than men at 3-months, regardless of other preclinical and clinical factors during the acute phase. These relationships seem to be mediated by atrial dysfunction and inflammation. The inflammatory response is slightly higher in women; however, there are no sex differences in their functional behavior. There is a probable relationship between the molecular marker of atrial dysfunction NT-proBNP and worse functional outcome in women, and the connection seems to be more important in cardioembolic stroke patients. In patients wi...

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 ...

Urine Arsenic and Arsenic Metabolites in U.S. Adults and Biomarkers of Inflammation, Oxidative Stress, and Endothelial Dysfunction: A Cross-Sectional Study
Conclusion: In a cross-sectional study of U.S. adults, we observed some positive associations of uAs and toenail As concentrations with biomarkers potentially relevant to CVD pathogenesis and inflammation, and evidence of a higher capacity to metabolize inorganic As was negatively associated with a marker of oxidative stress. https://doi.org/10.1289/EHP2062 Received: 14 April 2017 Revised: 13 November 2017 Accepted: 15 November 2017 Published: 15 December 2017 Address correspondence to S.F.

CNS Summit 2017 Abstracts of Poster Presentations
Conclusion: This novel technology discriminates and quantifies subtle differences in behavior and neurological impairments in subjects afflicted with neurological injury/disease. KINARM assessments can be incorporated into multi-center trials (e.g., monitoring stroke motor recovery: NCT02928393). Further studies will determine if KINARM Labs can demonstrate a clinical effect with fewer subjects over a shorter trial period. Disclosures/funding: Dr. Stephen Scott is the inventor of KINARM and CSO of BKIN Technologies.   Multiplexed mass spectrometry assay identifies neurodegeneration biomarkers in CSF Presenter: Chelsky...
