The cost of headache disorders in Europe: the Eurolight project.

Abstract: Background and purpose: Headache disorders are very common, but their monetary costs in Europe are unknown. We performed the first comprehensive estimation of how economic resources are lost to headache in Europe. Methods: From November 2008 to August 2009, a cross-sectional survey was conducted in eight countries representing 55% of the adult EU population. Participation rates varied between 11% and 59%. In total, 8412 questionnaires contributed to this analysis. Using bottom-up methodology, we estimated direct (medications, outpatient health care, hospitalization and investigations) and indirect (work absenteeism and reduced productivity at work) annual per-person costs. Prevalence data, simultaneously collected and, for migraine, also derived from a systematic review, were used to impute national costs. Results: Mean per-person annual costs were €1222 for migraine (95% CI 1055–1389; indirect costs 93%), €303 for tension-type headache (TTH, 95% CI 230–376; indirect costs 92%), €3561 for medication-overuse headache (MOH, 95% CI 2487–4635; indirect costs 92%), and €253 for other headaches (95% CI 99–407; indirect costs 82%). In the EU, the total annual cost of headache amongst adults aged 18–65 years was calculated, according to our prevalence estimates, at €173 billion, apportioned to migraine (€111 billion; 64%), TTH (€21 billion; 12%), MOH (€37 billion; 21%) and other headaches (€3 billion; 2%). Using the 15% systematic review prevalence of migraine, calculated costs were somewhat lower (migraine €50 billion, all headache €112 billion annually). Conclusions: Headache disorders are prominent health-related drivers of immense economic losses for the EU. This has immediate implications for healthcare policy. Health care for headache can be both improved and cost saving.

Nutrient sensing and TOR signaling in yeast and mammals

Abstract: Coordinating cell growth with nutrient availability is critical for cell survival. The evolutionarily conserved TOR (target of rapamycin) controls cell growth in response to nutrients, in particular amino acids. As a central controller of cell growth, mTOR (mammalian TOR) is implicated in several disorders, including cancer, obesity, and diabetes. Here, we review how nutrient availability is sensed and transduced to TOR in budding yeast and mammals. A better understanding of how nutrient availability is transduced to TOR may allow novel strategies in the treatment for mTOR-related diseases.

Experimental evolution of parasites

Abstract: Serial passage experiments are a form of experimental evolution that is frequently used in applied sciences; for example, in vaccine development. During these experiments, molecular and phenotypic evolution can be monitored in real time, providing insights into the causes and consequences of parasite evolution. Within-host competition generally drives an increase in a parasite's virulence in a new host, whereas the parasite becomes avirulent to its former host, indicating a trade-off between parasite fitnesses on different hosts. Understanding why parasite virulence seldom escalates similarly in natural populations could help us to manage virulence and deal with emerging diseases.

In utero undernourishment perturbs the adult sperm methylome and intergenerational metabolism

Abstract: Adverse prenatal environments can promote metabolic disease in offspring and subsequent generations. Animal models and epidemiological data implicate epigenetic inheritance, but the mechanisms remain unknown. In an intergenerational developmental programming model affecting F2 mouse metabolism, we demonstrate that the in utero nutritional environment of F1 embryos alters the germline DNA methylome of F1 adult males in a locus-specific manner. Differentially methylated regions are hypomethylated and enriched in nucleosome-retaining regions. A substantial fraction is resistant to early embryo methylation reprogramming, which may have an impact on F2 development. Differential methylation is not maintained in F2 tissues, yet locus-specific expression is perturbed. Thus, in utero nutritional exposures during critical windows of germ cell development can impact the male germline methylome, associated with metabolic disease in offspring.
