Introduction: Anxiety disorders have a lifetime prevalence of 34% with a similar level of heritability (31%) yet lack objective markers that could differentiate patients with underlying conditions. Up to 60%-70% of patients with Ehlers-Danlos syndrome have anxiety that meets criteria of generalized anxiety disorder, their clinical-DnA findings worth examining as biomarkers for patients with generalized anxiety. Method: Of the 1899 patients diagnosed with Ehlers-Danlos syndrome, 1261 were systematically evaluated for 80 history and 40 physical findings and separated into 826 who reported anxiety and 435 who did not. The most consistently reported or management-directing 60 of these clinical findings were, along with variations in genes relevant to these disorders, examined for association with anxiety. Results: Among the 30 anxiety- associated findings judged most predictive of Ehlers-Danlos syndrome in patients with anxiety were expected ones of adrenergic stimulation (difficulty concentrating-87% frequency and 1.26 anxiety/no anxiety ratio;chronic fatigue-84%, 1.17;sleep issues 69%, 1.52 that are criteria for generalized anxiety disorder) or of cholinergic suppression (e.g., frequent nausea 64%, 1.26). Less associated but more discriminating for underlying disease were those reflective of neuromuscular impact (e.g., chronic daily headaches 76%, 1.12);hypermobility (e.g., awareness of flexibility 72%, 1.03), or skin changes (e.g., elasticity around jaw 71%, 1.06). Anxiety-associated DnA variants included 54 of 88 in collagen type I/V/VII/IX genes, 14 of 16 in sodium channel sCn9A/10A/ 11A genes, 59 of 85 in POLG/MT-DnA genes, and 21 of 28 in profilaggrin- FLG genes that respectively impacted tissue laxity, sensory neural, autonomic-mitochondrial, and autonomic-inflammatory functions. Conclusion: Analysis of pathogenetic mechanisms in Ehlers-Danlos syndrome selected some 50 clinical-DnA findings useful for its diagnosis in those with generalized anxiety disorders.

This study presents an optimization of the Folin-Ciocalteu spectrophotometric method for the determination of total phenol content. Multivariate optimization using factorial planning 22 with a central point and central composite planning was constructed to evaluate the influence of variables in the process and maximize radiation absorption with minimal radiation scattering caused by solid formation. X-ray fluorescence and X-ray diffraction spectrometry were used to evaluate the chemical composition of solids formed and nephelometric and spectrophotometric studies were also used to evaluate whether the type, origin, dilution and dry extract contents of commercial propolis extracts would significantly influence the increase in radiation scattering and absorption. The optimized methodology added several advantages, such as reduction of reagents, time analysis, and higher accuracy.
