Asthma heartbreak, cranky economists, and prediction markets.

1. Childhood stress → Cortisol → Asthma Heartbreaking stories explain likely connections between difficult childhoods and asthma. Children in Detroit suffer a high incidence of attacks - regardless of allergens, air quality, and other factors. Peer-reviewed research shows excess cortisol may be to blame.

2. Prediction → Research heads up → Better evidence Promising technique for meta-research. A prediction market was created to quantify the reproducibility of 44 studies published in prominent psychology journals, and estimate likelihood of hypothesis acceptance at different stages. The market outperformed individual forecasts, as described in PNAS (Proceedings of the National Academy of Sciences.)

3. Fuzzy evidence → Wage debate → Policy fail More fuel for the minimum-wage fire. Depending on who you ask, a high minimum wage either bolsters the security of hourly workers or destroys the jobs they depend on. Recent example: David Neumark's claims about unfavorable evidence.

4. Decision tools → Flexible analysis → Value-based medicine Drug Abacus is an interactive tool for understanding drug pricing. This very interesting project, led by Peter Bach at Memorial Sloan Kettering, compares the price of a drug (US$) with its "worth", based on outcomes, toxicity, and other factors. Hopefully @drugabacus signals the future for health technology assessment and value-based medicine.

5. Cognitive therapy → Depression relief → Fewer side effects A BMJ systematic review and meta-analysis show that depression can be treated with cognitive behavior therapy, possibly with outcomes equivalent to antidepressants. Consistent CBT treatment is a challenge, however. AHRQ reports similar findings from comparative effectiveness research; the CER study illustrates how to employ expert panels to transparently select research questions and parameters.
