Health care provision is facing resourcing challenges which will further increase in the 21st century. Health care mediated by technology is widely seen as one important element in the struggle to maintain existing standards of care. Personal health monitoring and treatment systems with a high degree of autonomic operation will be required to support self-care. Such systems must provide many services...
Intragastric balloon has become a popular method for treatment of obesity due to its less-invasive and non-pharmaceutical procedure. In this method, a gas (or liquid)-filled balloon is inserted into the stomach using endoscopy or surgery. The balloon stays in and partially fills the stomach for a desired period of time to induce the feeling of satiety in the patient. At the end of the treatment period,...
This paper introduces a fuzzy logic approach to classifying the physical activity levels of obstructive sleep apnea (OSA) patients. Obesity is one of the risk factors of OSA, and the strong link between physical activity levels and obesity suggests that a method of assessing the physical activity levels of OSA patients is critical. We studied various objective and subjective instruments, and decided...
A modified genetic algorithm has been developed for the task of optimal parameter selection for compartmental models. As a case study, a predictive model of the emerging health threat of obesity in America was developed which incorporated varying levels of three treatment strategies in an attempt to decrease the amount of overweight Americans over a ten-year period. The genetic algorithm was then...
The development of obesity and diabetes is often attributable to a sedentary lifestyle, with a common therapeutic intervention being exercise.1 While the presumption has been that more strenuous workouts are more effective in the suppression of adipogenesis, here we show that 15 weeks of brief, daily exposure to high frequency, low magnitude mechanical signals suppresses adipogenesis by 26% in the...
Manipulation of gastric motility by gastric electrical stimulation (GES) has been suggested as a minimally invasive alternative treatment of gastric motility disorders and obesity. However, only neural GES (NGES) has been successful in invoking gastric contractions. Nevertheless, the relationship between these contractions and the controlling NGES parameters has not been quantified. We aimed at determining...
The obesity epidemic is one of the most rapidly evolving public health problems of our day. At present, 2/3 of American adults and 1/6 of American children and adolescents are considered either overweight or obese. Public health concern about obesity is high and reflects documented increased risk of cardiovascular disease, type 2 diabetes, many forms of cancer, gallbladder disease, and osteoarthritis,...
A major national health concern is the rapidly increasing incidence of obesity among people of all ages. Overweight conditions are associated with a wide variety of health problems, and costs associated with dealing with this issue are expected to be very high. Obesity offers opportunities for novel engineering approaches to deal with the diagnosis and treatment of the basic condition and related...
