TL;DR: Examination of the change in class differences between 1971 and 1981 for all causes of death combined and for the three categories of death which during these ages make a major contribution to total years of potential life lost shows complex changes.

TL;DR: A meta-analysis of genome-wide association studies and lead signals showed suggestive evidence of association with head circumference in infancy, indicating that a common genetic variant in this region might link early brain growth with neurological disease in later life.

TL;DR: A series of graphs is presented that show the estimated degree of bias in logistic coefficient estimates for two correlated continuous exposures measured with imprecision, indicating that even when the correlation coefficient between the exposure of interest and a correlated exposure is as low as 0.2, imprecISION in the measurement of the latter exposure can result in at least as serious bias in the logistic coefficients estimate.

TL;DR: It is suggested that BDNF genotype does not exert a major influence on the development of depression, following a systematic review and meta‐analysis of all association studies of these two BDNF polymorphisms and depression.

TL;DR: The heterogeneity in relationships between specific cancer sites and socioeconomic position suggests that no single factor--such as differences in general susceptibility or differences in smoking behaviour--can account for these associations, however socioeconomic differentials displayed by a particular malignancy do offer clues to its aetiology.
