Egg-yolk based supplements have demonstrated biological effects. We have developed a novel processed egg-yolk (PEY) complement, and we have tested whether it has inflammation modulatory properties. These were evaluated in a lipopolysaccharide (LPS)-challenge in 1-month male rats by in vivo circulating cytokine profiles measured by multiplexing techniques. Cell culture was used to explore ex vivo properties of derived serum samples. We explored growth factor composition, and mass-spectrometry metabolome and lipidome analyses of PEY to characterize it. PEY significantly prevented LPS-induced increase in IL-1 β, TNF-α, and MCP-1. Further, serum from PEY-treated animals abrogated LPS-induced iNOS build-up of the Raw 264.7 macrophage-like cell line. Immunochemical analyses demonstrated increased concentrations of insulin-like growth factor 1 (IGF-1), connective tissue growth factor (CTGF), and platelet-derived growth factor (PDGF) in the extract. PEY vs. egg-yolk comparative metabolomic analyses showed significative differences in the concentrations of at least 140 molecules, and in 357 in the lipidomic analyses, demonstrating the complexity of PEY. Globally, PEY acts as an orally-bioavailable immunomodulatory extract that may be of interest in those conditions associated with disarranged inflammation, such as inflammaging.

Does the presence of pressure ulcers entail "high risk of negative outcomes" in geriatric rehabilitation? Results from a retrospective cohort study. ResumenObjetivo: se realizó un estudio de cohorte retrospectivo para evaluar la prevalencia de úlceras por presión (PRU) en pacientes mayores ingresados en una unidad de rehabilitación geriátrica de postagudos (atención intermedia) e investigar el impacto de la presencia de PrU en los resultados clínicos del proceso de rehabilitación. Métodos: se estudiaron 668 pacientes ingresados de forma consecutiva, de enero de 2010 a diciembre de 2011. Se evaluó el impacto de la presencia de PrU en el momento del ingreso en relación a los siguientes resultados de salud: destino final, estado funcional, mortalidad y duración de la estancia en la unidad de rehabilitación. Resultados: la prevalencia de PrU en el momento del ingreso fue del 16%. Los pacientes con PrU tenían mayor edad, más presencia de discapacidad y tenían una mayor prevalencia de condiciones complejas, incluyendo desnutrición y deterioro cognitivo. En el análisis bivariado se encontró que los pacientes con PrU al ingreso presentaron un peor resultado final (%): alta a domicilio (69,2 vs. 82,5), ingreso en unidades de larga estancia (14 vs. 6,4), reingreso hospitalario (8,4 vs. 6,2) y fallecimiento (8,4 vs. 4,8); p < 0,001, y un peor índice de Barthel al momento del alta (57 frente a 83); p < 0,001, con mayor duración de la estancia en la unidad (61 frente a 53 días); p 0,004. En el análisis multivariante, la presencia de PrU en el momento del ingreso, se asoció como variable predictora negativa de retorno a domicilio, así como predictora negativa respecto a la ganancia funcional al alta de la unidad postagudos. Conclusiones: las PrUs fueron prevalentes y tuvieron un impacto negativo en los resultados clínicos de nuestra unidad geriátrica, como destino de alta, ganancia funcional y duración de la estancia, en pacientes vulnerables. AbstractAim: A retrospective cohort study was performed in order to evaluate the prevalence of pressure ulcers (PrUs) in older patients admitted to a geriatric rehabilitation unit of a postacute care hospital and to investigate the impact of the presence of PrUs on clinical outcomes of the rehabilitation process. Methods: We studied 668 post-acute patients consecutively attended, from January 2010 to December 2011. The effect of having PrUs at admission was evaluated based on its impact on outcomes: final destination, functional status, mortality and length of stay in the rehabilitation unit. Results: PrUs prevalence at admission was 16%. Patients with PrUs were older, more disabled and had more complex conditions, including malnutrition and cognitive impairment. In the bivariate analysis, we found patients with PrUs at admission had worst final outcome (%): discharge home (69.2 vs. 82.5), discharge long term care setting (14 vs. 6.4), discharge acute care (8.4 vs. 6.2) and dea...

Chicken egg yolk is a rich source of nutrients. These nutrients play an important role in a large set of vital activities and its components possess numerous physiological benefits, particularly the anti-inflammatory capacity. We have developed a novel processed-egg-yolk (PEY) complement with a proven anti-inflammatory effect in vivo associated to a higher proportion of growth factors, including connective tissue growth factor (CTGF), platelet-derived growth factor (PDGF), and insulin-like growth factor (IGF-1), than egg yolk. In this study we want to test the putative beneficial effects of PEY administration in the treatment of hair loss, not only when administered alone but also when administered together with common treatments of alopecia. Our results indicate a potent beneficial effect of PEY treatment in alopecic patients in both administration regimens. Treated subjects experimented hair regrowth, stop of hair loss and a better skin and hair condition. Moreover, the 100% natural origin of PEY prevents the appearance of side effects. Together, these results point to the oral PEY treatment as a promising treatment for alopecia. Moreover, this study adds to the growing scientific data demonstrating that natural components, such as curcumin and omega-3 fatty acids, can exert important anti-inflammatory and regenerative effects and should be introduced in the clinical practice as a complement to improve the efficacy of health treatments in humans.
