Après avoir sacrifié longtemps aux dieux virils (Mars, Apollon, Mercure) Clio se tourne de plus en plus vers les autels des déesses-mères : Cérès, Vénus, Genitrix… Cette image, qui nous est inspirée par le titre d'un des ouvrages utilisés ci-dessous, traduit, à sa manière, l'évolution de la recherche historique, depuis sa seconde naissance au XIXe siècle. Est-ce une simple mode, comme, naguère, l'engouement pour les livres de raison ? Non, sans doute. Histoire agraire et démographie constituent le tuf de l'histoire tout court. Elles appellent d'ailleurs, à cause de leur caractère total, la coordination des efforts et l'établissement de plans d'enquête rigoureux. A un niveau plus modeste, ce que nous essayerons ici, c'est de confronter un certain nombre de travaux récents hollandais, belges et français, tant du point de vue de leurs méthodes que du point de vue de leurs résultats.

When the identity or difference of position of two lines, bright or dark, in the spectra of two lights from different sources has to be compared with the utmost degree of accuracy, they are admitted simultaneously into different but adjacent parts of the slit of a spectroscope and viewed together. It was thus, for instance, that Dr. Huggins proceeded in determining the radial component of the velocity of the heavenly bodies relatively to the earth. It is requisite that the two lights that are to be compared should fall in a perfectly similar manner on the s lit: and it will be seen, from a perusal of his paper, how careful Dr. Huggins was in this respect.

Abstract Background: Previous observational studies showed that there was a conflict about serum iron status and the risk of breast cancer, which could have an impact on the prevention of breast cancer.Object: We used a two sample Mendelian randomisation (MR) study to explore the causal relationship between iron status and the risk of breast cancer.Method: To select single nucleotide polymorphisms (SNPs) which could be used as instrumental variables for iron status, we used the Genetics of Iron Status consortium. Moreover, we used the OncoArray network to select SNPs of instrumental variables for the outcome (breast cancer). The conservative instruments (SNPs were all consistent with iron status) and liberal instruments (SNPs was associated with at least one of iron status) were used in MR analysis. In the conservative instruments set we used an inverse-variance weighted (IVW) approach, and in the liberal instruments set we used the IVW, MR-Egger regression, weighted median and simple mode approach. Results: In the conservative approach, none of the iron status were statistically significant for breast cancer or its subtypes. And in the liberal approach, transferrin was positively associated with ER-negative breast cancer by simple mode (OR for MR: 1.225; 95% CI: 1.064, 1.410; P=0.030). However, other iron statuses had no association with breast cancer or its subtypes (P>0.05).Conclusion: Our MR study, in the liberal approach, suggested that changes in the concentration of transferrin could increase the risk of ER-negative breast cancer, and other iron statuses had no effect on breast cancer or its subtypes. This could be verified in future studies.
