Personalized Metabolic Avatar: A Data Driven Model of Metabolism for Weight Variation Forecasting and Diet Plan Evaluation.

Development of predictive computational models of metabolism through mechanistic models is complex and resource demanding, and their personalization remains challenging. Data-driven models of human metabolism would constitute a reliable, fast, and continuously updating model for predictive analytics. Wearable devices, such as smart bands and impedance balances, allow the real time and remote monitoring of physiological parameters, providing for a flux of data carrying information on user metabolism. Here, we developed a data-driven model of end-user metabolism, the Personalized Metabolic Avatar (PMA), to estimate its personalized reactions to diets. PMA consists of a gated recurrent unit (GRU) deep learning model trained to forecast personalized weight variations according to macronutrient composition and daily energy balance. The model can perform simulations and evaluation of diet plans, allowing the definition of tailored goals for achieving ideal weight. This approach can provide the correct clues to empower citizens with scientific knowledge, augmenting their self-awareness with the aim to achieve long-lasting results in pursuing a healthy lifestyle.

Modern content and improvement of high cardiovascular risk strategy in reducing mortality from cardiovascular diseases

The article describes the modern content of the high-risk strategy, which, along with the population strategy, forms the basis of a set of measures to reduce mortality from cardiovascular diseases. The high cardiovascular risk strategy is carried out at the individual level in outpatient structures as a part of primary and secondary prevention of cardiovascular diseases, and is also implemented in hospitals when performing elective surgical procedures, including high-tech interventions. Improving this strategy within the framework of primary health care involves the development of a system of high-risk offices, telemedicine consulting, remote monitoring of physiological parameters on the basis of a regional medical information system, and in the future, on the basis of a uniform vertically integrated medical information system. The development of the high-risk strategy as a part of inpatient practice occurs through the further replication of high technologies and the implementation of new types of them.

Client Satisfaction with Telehealth in Assisted Living and Homecare.

The Evangelical Lutheran Good Samaritan Society launched LivingWell@Home (LW@H) to provide telehealth services to clients in assisted living and home healthcare. LW@H assures client safety through remote monitoring of physiological parameters and assessment of nonbiometric parameters. Public policies increasingly support aging in place by allowing older adults with greater levels of impairment avoid or delay nursing home placement through alternative services offered in assisted living facilities and home healthcare agencies. Provider organizations face challenges caring for frail seniors with complex medical needs. Telehealth services may be helpful in supporting frail seniors living at home. Seniors were recruited into a randomized trial. Telehealth services were provided to 820 experimental subjects. Control subjects (n=762) received usual care. Clients rated their satisfaction at three points in time postimplementation: baseline, 6 months, and 12 months. Fisher's exact test compared client ratings at each measurement interval. No statistically significant differences were found between experimental and control subjects at baseline. Statistically significant differences emerged at follow-up. Experimental subjects in home healthcare agencies reported higher levels of satisfaction relative to controls, whereas experimental subjects in assisted living facilities reported lower levels of satisfaction. Telehealth services increased the probability that clients will be more satisfied compared with those without telehealth in homecare agencies. The opposite effect resulted among assisted living residents. Value propositions among community-dwelling older adults may influence their satisfaction with telehealth services postimplementation. More research is needed to examine the clinical efficacy and cost-effectiveness of these services.

A low power bioimpedance module for wearable systems

In the emerging field of wearable systems for remote monitoring of physiological parameters, the measurement of bioimpedance has the potential to provide many useful information. On the other hand, in this scenario, an optimization of power consumption of the circuit is crucial. A low power architecture for the measurement of bioimpedance was identified in this work. It reduces the consumption in the most critical blocks of the system: the current driver, the signal sensing and the demodulator. The device was prototyped and electrically characterized. The compromise between power consumption reduction and the increase in electrical noise was analysed and an effective signal processing technique was developed, showing that it is possible to achieve a signal to noise ratio good enough to enable applications like respiration monitoring (breathing rate and amplitude) or cardiac output estimation. Preliminary tests on healthy subjects showed a good correlation with spirometer, for breathing monitoring, and with Doppler echocardiography, for cardiac output. Thanks to the good functionality and the reduced current consumption (750μA at 2.8V power supply was obtained with a discrete-components implementation) the module resulted suitable for the integration in wearable devices for remote monitoring of physiological parameters, or other low power applications.

A generic telemedicine infrastructure for monitoring an artificial pancreas trial

Telemedicine systems are seen as a possible solution for the remote monitoring of physiological parameters and can be particularly useful for chronic patients treated at home. Implementing those systems however has always required spending a great effort on the underlying infrastructure instead of focusing on the application cores as perceived by their users. This paper proposes an abstract unifying infrastructure for telemedicine services which is loosely based on the multi-agent paradigm. It provides the capability of transferring to the clinic any remotely acquired information, and possibly sending back updates to the patient. The infrastructure is a layered one, with the bottom layer acting at the data level and implemented in terms of a software library targeting a wide set of hardware devices. On top of this infrastructure several services can be written shaping the functionality of the telemedicine application while at the highest level, adhering to a simple agent model, it is possible to reuse those functional components porting the application to different platforms. The infrastructure has been successfully used for implementing a telemonitoring service for a randomized controlled study aimed at testing the effectiveness of the artificial pancreas as a treatment within the AP@home project funded by the European Union.

Randomised Comparison of Remote Monitoring Versus Enhanced Standard Care for Heart Failure

Background: The role of remote physiological monitoring compared with nurse led clinics for the management of HF patients remains to be clarified. Methods: We conducted a randomised controlled trial comparing Enhanced Standard Care (ESC) delivered by a nurse led clinic versus remote monitoring of physiological parameters (RM). Inclusion criteria were one hospitalisation for HF in the preceding six months or three prior HF admissions. Following training inHF home management, patients were randomised to an ESC group managed by a nurse led heart failure clinic or to an RM Group who were issued with a device recording physiological parameters with trends checked daily by a medical officer. Evaluations in both groups included monthly health checks, NYHA status, current medications and compliance, and quality of life data. The primary o d h t

Smart Vest: Wearable multi-parameter remote physiological monitoring system

The wearable physiological monitoring system is a washable shirt, which uses an array of sensors connected to a central processing unit with firmware for continuously monitoring physiological signals. The data collected can be correlated to produce an overall picture of the wearer's health. In this paper, we discuss the wearable physiological monitoring system called ‘Smart Vest’. The Smart Vest consists of a comfortable to wear vest with sensors integrated for monitoring physiological parameters, wearable data acquisition and processing hardware and remote monitoring station. The wearable data acquisition system is designed using microcontroller and interfaced with wireless communication and global positioning system (GPS) modules. The physiological signals monitored are electrocardiogram (ECG), photoplethysmogram (PPG), body temperature, blood pressure, galvanic skin response (GSR) and heart rate. The acquired physiological signals are sampled at 250 samples/s, digitized at 12-bit resolution and transmitted wireless to a remote physiological monitoring station along with the geo-location of the wearer. The paper describes a prototype Smart Vest system used for remote monitoring of physiological parameters and the clinical validation of the data are also presented.
