Great sources of concern for pediatric and neonatal intensive care units are the total resource utilization and cost of caring for very sick children. This paper attempts to create a usable clinical decision support system (PEPCOR) that would help improve personalized health care and avoid unnecessary secondary, and costly, procedures that do not improve the care of a critically ill patient. The system...
The problem of missing data has made it difficult to analyze Electronic Health Records (EHR). In EHR data, the “missingness” often results from the low-rank property: each patient is considered a mixture of prototypical patients, and certain types of patients will have similar missing entries in their records. However, most existing methods to deal with missing data fail to capture this low-rank property...
Children diagnosed with cerebral palsy (CP) appear to be at high risk for developing neurobehavioral and motor disorders. The most common disorders for these children are impaired visual-perception skills and motor planning. Besides, they often have impaired executive functions, which can contribute to problematic emotional adjustment such as depression. Additionally, literature suggests that the...
Sickle cell disease (SCD) is the most common inherited disease, and SCD symptoms impact functioning and well-being. For example, adolescents with SCD have a higher tendency of psychological problems than the general population. Acceptance and Commitment Therapy (ACT), a cognitive-behavioral therapy, is an effective intervention to promote quality of life and functioning in adolescents with chronic...
Traumatic brain injury (TBI) is one of the leading causes of death and disability in the age group of 0 – 44 years. Though physical exercises have proven benefits in the rehabilitation process, the compliance rate of patients in the home environment is poor. In this paper we propose a system, MotionTalk, which captures and analyses motion data acquired using Microsoft Kinect. It is designed to give...
Sickle cell disease, the most common hemoglobin disorder, affects major organ systems with symptoms of pain, anemia and a multitude of chronic conditions. For adolescents, the disease adversely affects school attendance, academic progress and social activity. To effectively study the relationship among school attendance and other factors like demographics and academic performance, studies have relied...
This paper reviews challenges and opportunities in multiscale data integration for biomedical informatics. Biomedical data can come from different biological origins, data acquisition technologies, and clinical applications. Integrating such data across multiple scales (e.g., molecular, cellular/tissue, and patient) can lead to more informed decisions for personalized, predictive, and preventive medicine...
Sickle cell disease, the most common hemo-globinopathy in the world, affects patient lives from early childhood. Effective care of sickle cell disease requires frequent medical monitoring, such as tracking the frequency, severity, and duration of painful events. Conventional monitoring includes paper- or web-based reporting diaries. These systems require that patients carry forms, which are easily...
After receiving cancer treatment, patients often experience a decline of HRQoL (health-related quality of life). Physicians typically evaluate HRQoL during periodic clinical visits. However, out-patient reporting of vital signals between two visits could be used to interpret the decline of HRQoL. Considering that the vast majority of patients recovering from cancer are not in hospitals, it is often...
Doctors need fast and convenient access to medical data. This motivates the use of mobile devices for knowledge retrieval and sharing. We have developed TissueWikiMobile on the Apple iPhone and iPad to seamlessly access TissueWiki, an enormous repository of medical histology images. TissueWiki is a three terabyte database of antibody information and histology images from the Human Protein Atlas (HPA)...
Tongue Drive System (TDS) is an unobtrusive, wireless, and wearable device that allows for real time tracking of the tongue motion in the oral space for communication, control, and navigation applications. Utilizing the TDS, we were able to assess the use of tongue motion as a voluntary motor modality and its effect on the human performance in a realistic environment. Preliminary human trials were...
This paper presents a new magnetic localization system based on a compact triangular sensor setup and three different optimization algorithms, intended for tracking tongue motion in the 3-D oral space. A small permanent magnet, secured on the tongue by tissue adhesives, will be used as a tracer. The magnetic field variations due to tongue motion are detected by a 3-D magneto-inductive sensor array...
Tongue Drive System (TDS) is a tongue operated, unobtrusive, minimally invasive, wireless assistive technology (AT), which can enable people with severe disabilities to control different devices using their tongue motion. TDS can translate specific tongue movements into user-defined commands by detecting the position of a small permanent magnetic tracer attached to the users' tongue. We have built...
