An Analysis of Rate of Progression and Associated Risk Factors of Chronic Kidney Disease of Uncertain Etiology in Sri Lanka.

Chronic kidney disease of uncertain etiology (CKD-u) is an important public health issue in Sri Lanka and around the world, but published evidence of the progression of this disease is scanty. Our aim is to analyze the progression patterns and the associated risk factors of definite and probable CKD-u cases. This observational study was based on records of CKD-u cohort from 2005-14 at Girandurukotte, an endemic area for CKD-u in Uva Province, Sri Lanka.

Trace elements in native and improved paddy rice from different climatic regions of Sri Lanka: implications for public health.

Background: Samples of 226 new improved and 21 indigenous rice ( L.) varieties were collected from the rice fields in three climatic zones of Sri Lanka and concentrations of 18 trace elements (Li, B, Al, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Sr, Mo, Cd, Ba, Pb and Bi) were measured giving particular emphasis on Se, Cd and As using ICP-MS. The two way multivariate analysis of variance (MANOVA) method was employed to identify the differences in composition among rice from different climatic zones.
