Context: The 2010 maternal mortality rate per 100,000 births for Guinea is 680. This is compared with 859.9 in 2008 and 964.7 in 1990. The under 5 mortality rate, per 1,000 births is 146 and the neonatal mortality as a percentage of under 5s mortality is 29. In Guinea the number of midwives per 1,000 live births is 1 and the lifetime risk of death for pregnant women is 1 in 26. Guinea has the second highest prevalence of female genital mutilation in the world.
Question: Is the maternal mortality rate in Guinea higher in 2010 or 2008?

Ex Output:
2008

Context: Telomeres may regulate human disease by at least two independent mechanisms. First, replicative senescence occurs once short telomeres generate DNA-damage signals that produce a barrier to tumor progression. Second, telomere position effects (TPE) could change gene expression at intermediate telomere lengths in cultured human cells. Here we report that telomere length may contribute to the pathogenesis of facioscapulohumeral muscular dystrophy (FSHD). FSHD is a late-onset disease genetically residing only 25-60 kilobases from the end of chromosome 4q. We used a floxable telomerase to generate isogenic clones with different telomere lengths from affected patients and their unaffected siblings. DUX4, the primary candidate for FSHD pathogenesis, is upregulated over ten-fold in FSHD myoblasts and myotubes with short telomeres, and its expression is inversely proportional to telomere length. FSHD may be the first known human disease in which TPE contributes to age-related phenotype.
Question: Which disease is associated with the ectopic expression of the protein encoded by the gene DUX4?
