Elevated protein concentrations in newborn blood and the risks of autism spectrum disorder, and of social impairment, at age 10 years among infants born before the 28th week of gestation
Among the 1 of 10 children who are born preterm annually in the United States, 6% are born before the third trimester. Among children who survive birth before the 28th week of gestation, the risks of autism spectrum disorder (ASD) and non-autistic social impairment are severalfold higher than in the general population. We examined the relationship between top quartile inflammation-related protein concentrations among children born extremely preterm and ASD or, separately, a high score on the Social Responsiveness Scale (SRS total score ≥65) among those who did not meet ASD criteria, using information only from the subset of children whose DAS-II verbal or non-verbal IQ was ≥70, who were assessed for ASD, and who had proteins measured in blood collected on ≥2 days (N = 763). ASD (N = 36) assessed at age 10 years is associated with recurrent top quartile concentrations of inflammation-related proteins during the first post-natal month (e.g., SAA odds ratio (OR); 95% confidence interval (CI): 2.5; 1.2–5.3) and IL-6 (OR; 95% CI: 2.6; 1.03–6.4)). Top quartile concentrations of neurotrophic proteins appear to moderate the increased risk of ASD associated with repeated top quartile concentrations of inflammation-related proteins. High (top quartile) concentrations of SAA are associated with elevated risk of ASD (2.8; 1.2–6.7) when Ang-1 concentrations are below the top quartile, but not when Ang-1 concentrations are high (1.3; 0.3–5.8). Similarly, high concentrations of TNF-α are associated with heightened risk of SRS-defined social impairment (N = 130) (2.0; 1.1–3.8) when ANG-1 concentrations are not high, but not when ANG-1 concentrations are elevated (0.5; 0.1–4.2)

Saving Behavior and Portfolio Choice After Retirement
This paper reviews the literature on saving behavior and portfolio choice after retirement and provides a descriptive analysis of this behavior by Dutch elderly households. Studying saving behavior in the Netherlands is informative because of the very different institutional background compared to the US, for which most of the empirical evidence is. In the Netherlands, the generous pension system and almost complete coverage of the public health- and long-term care insurance system makes precautionary saving less necessary. Using detailed administrative data, we present evidence on the extent to which the financial resources of retirees are affected by shocks such as the decease of a spouse or deteriorating health—similar to recent empirical studies by Poterba et al. (Explorations in the economics of aging. University of Chicago Press, Chicago, pp 23–69, 2011; Investigations in the economics of aging. University of Chicago Press, Chicago, pp 21–69, 2012; Discoveries in the economics of aging. University of Chicago Press, Chicago, pp 159–186, 2014) for the US. Moreover, we examine the extent to which retirees who do not experience any shocks are able to keep positive wealth at their disposal and sustain their consumption level during retirement. Our results show that the death of the spouse results in a significant reduction of household wealth compared to surviving couples—which is also found in the US—while health shocks result in higher household savings in old-age due to the almost complete coverage of health care expenditures. Although retirees in the Netherlands face limited uncertainty about health expenditures, our analysis shows that the elderly, on average, keep large amounts of assets even at a very old age. Our findings suggest that (1) the generous pension benefits are protective of household wealth, (2) illiquid housing wealth constrains the decumulation of household wealth, (3) bequests and transfers after the death of the first spouse are important
