Exercise periodic breathing (EPB) is associated with exercise intolerance and poor prognosis in patients with heart failure (HF). However, EPB detection during cardiopulmonary exercise test (CPET) is difficult. The present study investigated the use of a wireless monitoring device to record the EPB during CPET and proposed quantization parameter estimates for the EPB. A total of 445 patients with HF were enrolled and underwent exercise tests. The ventilation data from the wearable device were compared with the data obtained during the CPET and were analyzed based on professional opinion and on 2 automated programs (decision tree [DT] and oscillatory pattern methods)...

OBJECTIVE: To assess the long-term efficacy of antireflux surgery on Barrett's esophagus (BE) using BRAVO wireless pH monitoring. BACKGROUND: BE is associated with chronic gastroesophageal reflux and esophageal cancer. Till date, studies have failed to demonstrate that preventing gastroesophageal reflux with antireflux surgery halts the progression of BE, often because of difficulties in objectively proving an effective antireflux barrier. METHODS: Since 1991, all patients undergoing antireflux surgery across 2 hospital sites have been followed in a prospective database...

Continuous patient monitoring systems acquire enormous amounts of data that is either manually analysed by doctors or automatically processed using intelligent algorithms. Sections of data acquired over long period of time can be corrupted with artefacts due to patient movement, sensor placement and interference from other sources. Owing to the large volume of data these artefacts need to be automatically identified so that the analysis systems and doctors are aware of them while making medical diagnosis. Three important factors are explored that must be considered and quantified for the design and evaluation of automatic artefact identification algorithms: signal quality, interpretation quality and computational complexity...

Wireless sensor networks (WSNs) are being used in a wide range of applications for healthcare monitoring, like heart rate monitors and blood pressure monitors, which can minimize the need for healthcare professionals. In medical system, sensors on or in patients produce medical data which can be easily compromised by a vast of attacks. Although signature schemes can protect data authenticity and data integrity, when the number of users involved in the medical system becomes huge, the bandwidth and storage cost will rise sharply so that existing signature schemes are inapplicability for WSNs...

BACKGROUND: The brain, made up of billions of neurons and synapses, is the marvelous core of human thought, action and memory. However, if neuronal activity manifests into abnormal electrical activity across the brain, neural behavior may exhibit synchronous neural firings known as seizures. If unprovoked seizures occur repeatedly, a patient may be diagnosed with epilepsy. PURPOSE: The scope of this project is to develop an ambulatory seizure monitoring system that can be used away from a hospital, making it possible for the user to stay at home, and primary care personnel to monitor a patient's seizure activity in order to provide deeper analysis of the patient's condition and apply personalized intervention techniques...

Despite having the basic tools necessary to appropriately identify and manage individuals with hypertension for over half a century it remains the single greatest contributing risk factor to morbidity and mortality worldwide today. Since diagnosis and effective treatment availability are not issues, this major failing in care can be attributed to inadequate systems of care: systems that have led to only <20% of hypertensive individuals globally having their blood pressure adequately controlled. Even in the US, where it is one of the most common reasons for a primary care visit, and with over $42...

Neurosurgical ventricular shunts inserted to treat hydrocephalus experience a cumulative failure rate of 80 % over 12 years; obstruction is responsible for most failures with a majority occurring at the proximal catheter. Current diagnosis of shunt malfunction is imprecise and involves neuroimaging studies and shunt tapping, an invasive measurement of intracranial pressure and shunt patency. These patients often present emergently and a delay in care has dire consequences. A microelectromechanical systems (MEMS) patency sensor was developed to enable direct and quantitative tracking of shunt patency in order to detect proximal shunt occlusion prior to the development of clinical symptoms thereby avoiding delays in treatment...

BACKGROUND: Sustained cardiac rehabilitation is the key intervention in the prevention and treatment of many human diseases. However, implementation of exercise programs can be challenging because of early fatigability in patients with chronic diseases, overweight individuals, and aged people. Current methods of fatigability assessment are based on subjective self-reporting such as rating of perceived exertion or require specialized laboratory conditions and sophisticated equipment. A practical approach allowing objective measurement of exercise-induced fatigue would be useful for the optimization of sustained delivery of cardiac rehabilitation to improve patient outcomes...

Chronic respiratory diseases are one of the most prevalent health problems in the world. Treatment for these kind of afflictions often take place at home, where the continuous care of a medical specialist is frequently beyond the economical means of the patient, therefore having to rely on informal caregivers (family, friends, etc.). Unfortunately, these treatments require a deep involvement on their part, which results in a heavy burden on the caregivers' routine and usually end up deteriorating their quality of life...
