Use cholinesterase activity environmental monitoring

Agricultural pesticide handlers are at an elevated risk for overexposure to organophosphate OP pesticides, but symptoms can be difficult to recognise, making biomarkers invaluable for diagnosis.

Use cholinesterase activity environmental monitoring

The experience of recent military conflicts indicates that highly trained medical personnel and combat casualty care physicians, at all levels in the theater, from the far-forward to field hospital to rehabilitation centers, are able to save lives of wounded soldiers at unprecedented rates.

However, evolving asymmetric threats and smaller, more Use cholinesterase activity environmental monitoring military operations may not have the advantage of the organized logistics and casualty care systems and will rely on self- and buddy-care.

In environmental monitoring, it is of fundamental importance to fully characterize the enzymatic form present in exposed organisms, and to know the normal range of activity in non-exposed individuals. Guidelines have been developed for physicians involved in the surveillance of workers with potential exposure to organophosphates, using serial monitoring of cholinesterase enzyme activity in the blood.

Therefore, new medical technologies are needed to advance warfighter medical skills in primary and combat casualty care. In the last few years, remarkable progress has been achieved in personalized medicine, wearable physiological and activity sensors, mobile computing, bioinformatics and computational medicine.

All of these technologies could be integrated in an advanced platform, a Warrior Health Avatar, to support growing demands for preventive and primary medical military health care as well as acute and combat trauma care. In spite of spectacular progress in wearable, non-invasive biomedical sensor technology, which can collect large amount of physiological, physical activity and environmental data, there are no established methods to utilize that data in a predictive fashion [Friedl ].

Typical physiological sensor data processing algorithms involve data mining and stochastic correlations which have limited predictive capability. Personalized medicine is becoming the cornerstone of medical practice with prospects of the customization of healthcare - with medical decisions, practices, treatments tailored to the individual patient [KatsanisSnyderman ].

The use of genetic information and biomarkers has played a major role in personalized medicine in oncology and other chronic diseases such as asthma and diabetes [FDA ].

Effective deployment of personalized medicine is still limited by the diagnostic technology and limited capabilities of computational systems physiology and biology [XieReifman ].

For the model to be functional in military health care it should account for the subject specific body parameters such as gender, anthropometry, physical fitness, physiological vitals as well as other parameters used in contemporary personalized medicine.

Because of its potential complexity the models and software tool could be first developed on conventional computers.

However, the ultimate goal is to transition this technology to mobile computing platforms for the use by military medics and individual warfighters in the form of a Warrior Health Avatar. For this Avatar to be successful, it must be not only personal but also predictive, preventive, and participatory P4 [Hood ].

Therefore, the simulation framework and the user interface in particular, should be designed to demonstrate the capability to address the above P4 requirements and provide military medicine functionality such as: Visual setup of the human body anthropometric parameters and basic physiological vitals, Simulate one selected human body physiological system e.

Be portable to desktop and mobile computing systems, Provide user specific medic, warrior, and scientist graphical interface for model setup, execution, dynamic adjustment of parameters, interface to wearable sensors and analysis of results.

Development and deployment of such a framework will require collaboration between private, academia, and government teams and may have to accommodate both open source and commercial software components.

There are several ongoing programs in the US, Europe, and worldwide developing open source tools for various aspects of personalized medicine including genomics, e. Formulate and design the Warrior Health Avatar simulation framework, its key functionalities, main components, communication with wearable sensors and the user interface.

Develop and demonstrate prototype tools on selected desktop and mobile computing platforms. Prepare the Phase I final report describing details of the proposed simulation framework, preliminary results of relevant military applications, and rationale for further model development, validation and military deployment.

Develop and demonstrate a functional prototype of the Warrior Health Avatar. Develop interfaces to existing human anatomical, physiological and injury databases and models to enable model personalization and calibration.

Validate model components on available experimental and clinical data. Demonstrate the capability of model calibration on static and dynamic wearable sensor data.

Demonstrate the prototype Warrior Health Avatar to military medicine stakeholders. The Warrior Health Avatar will have immense potential application in military, veteran and civilian medicine. Successful proposers should envision the transition of this technology into military health system supporting warfighters from enlistment, to service, to discharge to the veteran system.

The target military users should include both military medics and individual warfighters. Interfaces to military physiological and injury wearable sensor and monitoring systems should be pursued.

The technology developed in this SBIR project could also support various civilian health systems in personalized health and medicine, in model-based management of chronic diseases, sports and performance medicine, drug discovery, clinical trials, geriatrics, rehabilitation, and many others.
