"An epoch-making and blessed moment in the history of medicine" -thoughts on international health equity and the Nobel prize in medicine.

The Nobel Prize in Physiology or Medicine is a prestigious award given every year for ostensibly the most important discovery in the field. Prizes in Medicine have typically gone to honor foundational knowledge rather than measurable impact. Two recent examples from global health (a rotavirus vaccine, child growth standards) offer alternatives for what might be lauded in medicine.

The vitamin D positive feedback hypothesis of inflammatory bowel diseases.

While it appears that there are a variety of factors that exacerbate IBD, it is frustrating that symptoms can persist and worsen even when environmental insults are removed. We suggest that there may be a positive feedback loop which perpetuates the inflammatory response in IBD patients. The loop is triggered by vitamin D deficiency which reduces calcium uptake.

A large-scale operational study of home-based therapy with ready-to-use therapeutic food in childhood malnutrition in Malawi.

Home-based therapy with ready-to-use therapeutic food (RUTF) for the treatment of malnutrition has better outcomes in the research setting than standard therapy. This study examined outcomes of malnourished children aged 6-60 months enrolled in operational home-based therapy with RUTF. Children enrolled in 12 rural centres in southern Malawi were diagnosed with moderate or severe malnutrition according to the World Health Organization guidelines.
