项目摘要

Project Summary Validation and Feasibility Non-Invasive Anemia Diagnostic Tool (ASIST Device) This project will establish the accuracy and feasibility of our novel non-invasive, portable, low- cost device to diagnose chronic nutritional and hemolytic anemia in resource poor areas. This device has the potential to mitigate the prevalence of anemia in LMICs, improving health outcomes, especially in pregnant women and adolescent girls. Despite increased attention from the WHO, anemia continues to be a formidable public health issue affecting a third of the world's population, with much of the disease burden in low- and middle- income countries (LMICs). Pregnant women and young children are the most vulnerable of these populations. Severe anemia in pregnancy contributes significantly to preventable morbidity and mortality both during pregnancy and in the delivery process. For the fetus of an anemic mother, there are long-term neurodevelopmental consequences. In resource-rich countries, anemia can be diagnosed using minimally invasive point of care devices and nutritional and hemolytic causes can be differentiated without invasive testing using exhaled Carbon Monoxide, a breakdown product of hemoglobin. In low- and middle-income countries (LMICs), where this type of testing is not readily available, the diagnosis of anemia is often inaccurate or missed all together. Based on the global burden of anemia, especially in LMICs, there is a need for a low-cost device that can non-invasively detect anemia and help to distinguish between nutritional and hemolytic causes to inform clinical decision making.

项目概要非侵入性贫血诊断工具（ASIST 设备）的验证和可行性该项目将确定我们新型非侵入式、便携式、低功耗的技术的准确性和可行性。在资源匮乏地区诊断慢性营养性和溶血性贫血的成本装置。这该设备有可能减轻中低收入国家贫血的患病率，改善健康状况结果，尤其是孕妇和少女。尽管世界卫生组织越来越重视，贫血仍然是一个令人畏惧的公共卫生问题这一问题影响着世界三分之一的人口，其中大部分疾病负担发生在低收入和低收入国家中等收入国家 (LMIC)。孕妇和幼儿是最脆弱的群体这些人口中。妊娠期严重贫血对可预防的贫血有显着贡献怀孕期间和分娩过程中的发病率和死亡率。对于胎儿来说贫血的母亲，有长期的神经发育后果。在资源丰富的国家，可以使用微创护理点诊断贫血无需侵入性测试即可区分设备以及营养和溶血原因呼出的一氧化碳是血红蛋白的分解产物。在低收入和中等收入国家在不易获得此类检测的国家（中低收入国家），贫血的诊断是经常不准确或全部遗漏。基于全球贫血负担，特别是在中低收入国家需要一种低成本设备，能够非侵入性地检测贫血并帮助区分营养和溶血原因，为临床决策提供信息。
