Metabolic features of chronic fatigue syndrome.

More than 2 million people in the United States have myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). We performed targeted, broad-spectrum metabolomics to gain insights into the biology of CFS. We studied a total of 84 subjects using these methods. Forty-five subjects (n = 22 men and 23 women) met diagnostic criteria for ME/CFS by Institute of Medicine, Canadian, and Fukuda criteria. Thirty-nine subjects (n = 18 men and 21 women) were age- and sex-matched normal controls. Males with CFS were 53 (±2.8) y old (mean ± SEM; range, 21-67 y). Females were 52 (±2.5) y old (range, 20-67 y). The Karnofsky performance scores were 62 (±3.2) for males and 54 (±3.3) for females. We targeted 612 metabolites in plasma from 63 biochemical pathways by hydrophilic interaction liquid chromatography, electrospray ionization, and tandem mass spectrometry in a single-injection method. Patients with CFS showed abnormalities in 20 metabolic pathways. Eighty percent of the diagnostic metabolites were decreased, consistent with a hypometabolic syndrome. Pathway abnormalities included sphingolipid, phospholipid, purine, cholesterol, microbiome, pyrroline-5-carboxylate, riboflavin, branch chain amino acid, peroxisomal, and mitochondrial metabolism. Area under the receiver operator characteristic curve analysis showed diagnostic accuracies of 94% [95% confidence interval (CI), 84-100%] in males using eight metabolites and 96% (95% CI, 86-100%) in females using 13 metabolites. Our data show that despite the heterogeneity of factors leading to CFS, the cellular metabolic response in patients was homogeneous, statistically robust, and chemically similar to the evolutionarily conserved persistence response to environmental stress known as dauer.

Enhanced Systemic Bioavailability of Curcumin Through Transmucosal Administration of a Novel Microgranular Formulation.

BACKGROUND/AIM: Curcumin is a promising nutraceutical for chemoprevention of head and neck squamous cell carcinoma (HNSCC). Capsular formulations of curcumin demonstrate low systemic bioavailability. We aimed to determine if curcumin levels were higher in healthy volunteers and cancer patients with microgranular curcumin that allows for transmucosal absorption and identify a consistent biomarker. PATIENTS AND METHODS: Eight healthy volunteers and 15 HNSCC patients completed the trials. Serum levels of curcumin were measured by HPLC. Biological activity of curcumin was assessed with Multiplex Immunoassay and immunohistochemistry. RESULTS: We achieved higher serum levels of curcumin compared to trials using capsular formulation. In cancer patients a significant decrease in expression of fibroblast growth factor-2 (FGF-2) in post-biopsy samples and decreased serum levels of FGF-2, granulocyte macrophage colony-stimulating factor (GM-CSF) and interleukin-17 (IL-17) (p<0.05) was observed. CONCLUSION: Transmucosal administration of microgranular curcumin leads to enhanced curcumin bioavailability that is associated with significant biological effects.

Hand-drumming to build community: the story of the Whittier Drum Project.

Over the years, the author participated in drum circles and classes in Denver, Fort Collins, and Boulder, Colorado. He noticed that drumming made him feel grounded and at peace. Drumming is very accessible, not like playing the piano or violin. Simple rhythms can be taught to people with no drumming experience very quickly and an ensemble rhythm created with a group in one sitting. Drumming turned out to be a highly effective way to engage with young people not only to address their individual spirits but to join with others to create a community.
