Symptom burden and health-related quality of life (HRQOL) are important predictors of how a disease affects patients’ lives, especially for endemic health problems such as chronic kidney disease of uncertain etiology (CKDu). Our study describes symptom burden, HRQOL, and associated demographic and clinical variables in CKDu patients in the Girandurukotte area, Sri Lanka. A cross-sectional study included 120 CKDu patients attending the renal clinic in the endemic area. The instruments applied were the Kidney Disease Quality of Life—Short Form (KDQOL-SFTM) version 1.3 and CKD Symptom Index—Sri Lanka. Socio-demographic, disease-related, and anthropometric variables were also investigated. The mean age of patients was 61.87 (SD 11.31), while 69.2% were male. The mean glomerular filtration rate was 28.17 (SD 14.03) mL/min/1.73 min2, and 70.8% were anemic. Bone/joint pain was the most experienced symptom while the median number of symptoms reported by patients was 5 (IQR 3–7). The mean symptom burden, physical component summary, mental component summary, and kidney-disease-specific component scores were 12.71 (SD 10.45), 68.63 (SD 19.58), 78.53 (SD 18.78), and 81.57 (SD 5.86), respectively. Age was found to be a significant predictor of HRQOL, while hemoglobin level and being a farmer were significant predictors of symptom burden. Our data indicate that CKDu patients in all stages experience at least one symptom affecting all aspects of HRQOL.
Rice (Oryza sativa) is the staple food in Sri Lanka. Being a country rich in biodiversity, over 3000 rice varieties have been reported in the country. This study was carried out to investigate the macronutrient composition and mineral composition of selected common traditional or heirloom rice varieties which were grown from ancient times in Sri Lanka. Six heirloom red pericarp rice varieties, one heirloom white pericarp rice variety, two genetically improved white pericarp rice varieties and one genetically improved red pericarp rice variety were collected representing all the agro-climatic zones of Sri Lanka. Five hundred grams each sample was cleaned, dehusked, ground and pooled to obtain a composite sample. The prepared rice samples were analyzed for measure the moisture, crude fat, crude protein, ash and total carbohydrate contents. Mineral composition was analyzed using inductive couple plasma mass spectrophotometry (ICP-MS). The results indicated that all the rice varieties tested were significantly not different by their carbohydrate contents. Total carbohydrate contents varied from 65.80±0.79% to 79.30±0.38%. Crude fat contents of rice varieties varied from 1.59±0.01% to 2.87±0.20%, crude protein contents varied from 7.60±0.20% to 9.31±0.63%, ash contents ranged from 0.84±0.03% to 2.95±0.01%. Red pericarp rice varieties were richer in crude fat, protein, ash and minerals such as Na, and Bi than white rice pericarp varieties. Further traditional rice varieties were richer in overall nutritional quality and in mineral composition compared to genetically improved white pericarp rice varieties. Traditional rice varieties are good sources to fulfill most of the daily mineral requirement of human. As an overall conclusion, red pericarp rice has more nutritional value than white pericarp rice. According to the results, some traditional varieties as well as red pericarp improved rice varieties are nutritionally important for human beings.
Coconut testa is the brown colour thin outer covering of the coconut endosperm. An attempt was made to convert chemical composition and nutritional properties of coconut Thambili, Ran Thambili and Tall × Tall were compared against defatted coconut parings of each cultivar were oven-dried and according to AOAC methods. The carbohydrate content was acids and micro-mineral distributions were also determined. cultivar was carbohydrate (42.55-59.24 %) followed by protein (23.82-32.22 %) and fat (7.93-23.49 %). Commercial hybrid had the highest carbohydrate content (59.24 %) while the minimum carbohydrate content was recorded for San Raman variety (42.55 %). Highest protein content was observed in Gon Thambili (32.22 %) variety while the least was observed in commercial hybrid (23.82 %). The highest fat content was noted in San Raman variety (23.49 %). Tall × Tall variety contained the least fat content (7.93 %). Maximum ash content was observed in Ran Thambili variety (5.30 %) while the least ash content was for Gon Thambili variety (3.70 %). Highest moisture content was prevalent in San Raman variety (4.27 %) while the least was observed in commercial hybrid (2.27 %). substance, which provides value addition to the under-utilised by-product of coconut processing industry.
The present investigation was carried out to determine the nutritional and functional properties of T. cucumerina. Water extracts of freeze dried flowers, fruits, and leaves of T. cucumerina were evaluated for their total phenolic content (TPC), total flavonoid content (TFC), antioxidant activity, α-amylase inhibitory activity, and fiber and mineral contents. Antioxidant activity, TPC, and TFC were significantly higher (P ≤ 0.05) in leaves than in flowers and fruits. A significant linear correlation was observed between the TPC, TFC, and antioxidant activities of plant extracts. Although, leaves and flower samples showed a significantly higher (P ≤ 0.05) amylase inhibitory activity than the fruit samples, the overall amylase inhibition was low in all three parts of T. cucumerina. Soluble and insoluble dietary fiber contents were significantly higher (P ≤ 0.05) in fruits than in flowers and leaves. Ca and K contents were significantly higher (P ≤ 0.05) in leaf followed by fruit and flower and Mg, Fe, and Zn contents were significantly higher (P ≤ 0.05) in leaves followed by flowers and fruits. In conclusion, T. cucumerina can be considered as a nourishing food commodity which possesses high nutritional and functional benefits for human health.
Fluoride is a beneficial trace element for human health as its deficiency and excess levels can cause detrimental health effects. In Sri Lanka, dry zone regions can have excessive levels of fluoride in drinking water and can cause dental and skeletal fluorosis. In addition to drinking water, traditional habits of tea consumption can cause an additional intake of fluoride in the population. A total number of 39 locally blended black tea samples were collected from a village where chronic kidney disease with undetermined origin (CKDu) is prevalent. In addition, unblended tea samples were obtained from tea-producing factories. The fluoride contents in infusions of 2% weight per volume (w/v) were measured using calibrated ion-selective fluoride electrodes. The mean fluoride content was 2.68±1.03 mg/L in loose tea, 1.87±0.57mg/L in packed tea samples, and 1.14±0.55 mg/L in unblended tea. Repeated brewing of the same tea leaves showed that over 50% of fluoride leached into the solution in the first infusion. An estimate of the daily total average fluoride intake via tea consumption per person is 2.68 mg per day. With groundwater in many dry zone regions in Sri Lanka showing high fluoride levels that exceed 0.5 mg/L, the additional daily intake can rapidly exceed recommended thresholds of 2 mg/day. This can add to adverse health impacts that might also relate to CKDu.
