Teleophthalmology: a strategy for timely diagnosis of sight-threatening diabetic retinopathy in primary care, Concepción, Chile

AIM: To estimate the prevalence of diabetic retinopathy(DR) in a diabetic population of the public health system. METHODS: This non-experimental, descriptive and crosssectional study, with no direct control over the variables analysed, was carried out by the Telemedicine Unit of the University of Concepción(TELMED) and the Family Health Centers(CESFAM) of the Health Service Concepción, Chile, among a population of 7382 diabetic patients of the public health system, from October 2014 to June 2015. Two digital images for each patient’s eyes were obtained and uploaded to the TELMED tele-ophthalmology platform. The images were remotely evaluated by a retina expert ophthalmologist for diagnosis. Treatment and a referral(if required) were recommended, and an individualised report for each patient was sent to the place of ***: The prevalence of DR in this study was 14.9%. Of these, 48.7% had mild non-proliferative DR(NPDR), 30.8% moderate NPDR, 15.9% severe NPDR, and 4.6% proliferative DR. Of the patients with DR, 17.8% were referred for fluorescein angiography, 4.3% for panretinal photocoagulation, 1.2% for vitrectomy, and 0.4% for cataract ***: The use of telemedicine allowed an increased screening coverage for DR in diabetic patients. The different types of DR were detected in a timely manner, decreasing waiting times due to the lack of specialists in ophthalmology in the public health system.

Excess Levels of ILysine and Threonine in Low Protein, Wheat-based Diets on Serum Amino Acid Concentrations and Performance of Growing Pigs

引用

Journal of Agricultural Science and Technology(A) 2012年第5期2卷 619-627页

Two experiments were conducted to evaluate the growth response and serum concentrations （SC） of amino acids （AA） in pigs fed wheat-based diets with either deficient, adequate or excess Lys and Thr. Previously, the standardized ileal digestibilities of AA in a basal diet were determined with five ileal cannulated pigs in a digestion trial. In experiment 1, 21 pigs （12.5±0.91 kg） were used to evaluate the effect of adding 0%, 0.69%, and 1.38% free L-Lys. The best growth response was obtained with 0.69% added L-Lys, equivalent to 1.05% total in the diet. The SC of Arg, Thr, and Val were lower （P 〈 0.05） in pigs fed the Lys adequate diet, compared to the deficient, but no further change occurred with excess Lys （P 〉 0.10）. Lys SC increased with each increment in the dietary Lys content （P 〈 0.05）. In experiment 2, 20 pigs （14.3 ± 1.57 kg） were used, and the addition of 0%, 0.14%, 0.28%, and 0.42% crystalline Thr, to the 0.69% L-Lys-supplemented basal diet, was evaluated. The best response was obtained with added 0.28% L-Thr, （0.66% total Thr）, but excess Thr reduced feed intake and growth rate. Moderate and excess levels of Yhr increased the SC of Thr, but excess reduced those of Va[ and Lys. These data show that excess Thr, but not Lys, affect the performance of growing pigs. Also, these data indicate that Val may become limiting in low protein diets with excess Lys or Thr.
