It's not what you know but who you know that's important: the influence of social networks on communities

Since its conception in 1945, the UK National Health Service (NHS) has been the focus of extensive political rhetoric regarding the involvement of patients and the public in the provision of health‐care services both locally and nationally. However, achieving substantial user involvement within local communities has proven to be a complex task. The exploratory research presented in this paper investigates the influence of social networks within local communities and its relevance for user involvement. Four main findings emerged: interviewees have strong informal social networks; there is a strong sense of generalized reciprocity; diversity is limited within the social groupings; and there exists a lack of trust in governmental institutions. With regards to health issues, there is an overriding feeling that ‘things like that should be left to the people who know’. If user involvement is to be achieved at the level envisioned by the UK government, achieving a greater relevance for users is essential.

The effect of vaccination on children's physical and cognitive development in the Philippines

We use data from the Cebu Longitudinal Health and Nutrition Survey (CLHNS) in the Philippines to link vaccination in the first 2 years of life with later physical and cognitive development in children. We use propensity score matching to estimate the causal effect of vaccination on child development. We find no effect of vaccination on later height or weight, but full childhood vaccination for measles, polio, Tuberculosis (TB), Diphtheria, Pertussis and Tetanus (DPT) significantly increases cognitive test scores relative to matched children who received no vaccinations. The size of the effect is large, raising test scores, on average, by about half an SD.

Deoxynivalenol (DON) in wheat: an example of weighing the pros and cons of food stuffs

A Committee of the Health Council of the Netherlands advised on deoxynivalenol (DON), a mycotoxin occurring in cereals. TDIs of 1.0 and 0.5?µg.kg_{body weight} ^?1.day^?1 have been based on mice and pig studies in which DON reduced growth. In 1999, the 50^th and 95^th percentiles of DON intake by 1‐4‐year‐old children were, respectively, 1.3 and 2.4?µg.kg_{body weight} ^?1.day^?1. The Committee considered: (i) TDI contains safety factors, (ii) a slightly reduced weight gain is not necessarily harmful, (iii) when growth rate is highest, children consume little or no wheat, and (iv) in real life, exposure varies, causing the effect to be smaller. The Committee concluded that an exposure that only incidentally exceeds—up to about five times—0.5?µg.kg_{body weight} ^?1.day^?1 very unlikely inhibits weight gain. More severe effects on immunity, fertility and the foetus may occur at intakes higher than 2.5µg.kg_{body weight} ^?1.day^?1. Nonetheless, toxin exposure should be kept as low as possible. The Committee advised to agriculturally reduce DON content; second one may exclude wheat with high DON content for human consumption. Limits of 500 and 100?µg/kg_wheat prevent exposure exceeding 1.5 and 0.5?µg.kg_{body weight} ^?1.day^?1, respectively. As wheat products are good sources of nutrients, the Committee advised against discouraging their consumption.
