Authentication of premium Asian rice varieties: stable isotope ratios and multi-elemental content for the identification of geographic fingerprints

Over 90 percent of the world's rice is produced and consumed in the Asia-Pacific region. Varieties such as Thai Jasmine rice and Paw San (or “Myanmar pearl rice”) are globally recognised as premium, while more local high-grade varieties include the Indonesian Ciherang and Inpari. Being able to trace the origin of these products has become necessary, since they are marketed at relatively higher prices compared to other cultivars, and they often become the target of fraudulent activities. In this work, we aimed to identify variables that could distinguish the premium-producing regions within each country, by Isotope Ratio Mass Spectrometry (IRMS) and Inductively Coupled Plasma- Mass Spectrometry (ICP-MS). Low-Level Data Fusion (LLDF) followed the analysis of more than 300 authentic samples, and (O)PLS-DA models yielded very high accuracy values. The most important geo-differentiating variables (VIP>1.4) were identified as: δ13C, δ18O, δ2H, δ34S, Co, Rb, Cu, Ba and Z

Accelerating health equity: the key role of universal health coverage in the Sustainable Development Goals.

The Sustainable Development Goals (SDGs), to be committed to by Heads of State at the upcoming 2015 United Nations General Assembly, have set much higher and more ambitious health-related goals and targets than did the Millennium Development Goals (MDGs). The main challenge among MDG off-track countries is the failure to provide and sustain financial access to quality services by communities, especially the poor. Universal health coverage (UHC), one of the SDG health targets indispensable to achieving an improved level and distribution of health, requires a significant increase in government investment in strengthening primary healthcare - the close-to-client service which can result in equitable access. Given the trend of increased fiscal capacity in most developing countries, aiming at long-term progress toward UHC is feasible, if there is political commitment and if focused, effective policies are in place. Trends in high income countries, including an aging population which increases demand for health workers, continue to trigger international migration of health personnel from low and middle income countries. The inspirational SDGs must be matched with redoubled government efforts to strengthen health delivery systems, produce and retain more and relevant health workers, and progressively realize UHC
