For newly diagnosed prostate cancer patients with a positive biopsy, there are a variety of treatment options to consider. To aid physicians and patients in their decision making, a variety of predictive assays have emerged within the last decade, many of them imaging based. These assays build predictive models for survival analysis to provide personalized risk assessments for the patients. However, there have rarely been any published studies on how the amount of tumor in the positive prostate biopsy affects the predictive power of these imaging based assays...

Concussion is currently a serious health problem and can lead to severe brain dysfunction. There is a definite need for sensitive and reliable tests to detect and evaluate the subtle changes in brain function caused by concussion. This study details the development of a low cost portable eye tracking device that can aid in the detection of concussions. The device evaluates ocular motor function and can be used on the sidelines of sporting events to give a quick indication of the severity of head trauma. It can further be used to evaluate and monitor mild Traumatic Brain Injuries and aid in the return to play decision making process...

Biomarker discovery involves finding correlations between features and clinical symptoms to aid clinical decision. This task is especially difficult in resting state functional magnetic resonance imaging (rs-fMRI) data due to low SNR, high-dimensionality of images, inter-subject and intra-subject variability and small numbers of subjects compared to the number of derived features. Traditional univariate analysis suffers from the problem of multiple comparisons. Here, we adopt an alternative data-driven method for identifying population differences in functional connectivity...

People with low vision have limited residual vision that can be greatly enhanced through high levels of magnification. Current assistive technologies are tailored for far field or near field magnification but not both. In collaboration with L.V. Prasad Eye Institute (LVPEI), a wearable, optical-digital assistive device was developed to meet the near and far field magnification needs of students. The critical requirements, system architecture and design decisions for each module were analyzed and quantified...

BACKGROUND: Structural collection of data from combat injuries is important to improve provided care and the outcome of (combat) casualties. Trauma registries are used in civilian and military health care systems for systematic administration of injury data. However, these registries often use different methods of data management, compromising international comparison of trauma systems. The aim of this review is to aid in reaching international (coalition-wide) consensus for compatible data collection methods with uniform definitions, which is needed for transnational research and subsequent improvement of medical support organizations...

For policymakers aiming to alter the migratory patterns of skilled labor, one potential tool involves subsidizing higher education. We present new evidence on the effects of merit aid scholarship programs - programs that offer partial or full tuition subsidies to high-achieving in-state students. Using Census data on 24 to 32 year olds in the U.S. from 1990 to 2010, we show that eligibility for merit aid programs slightly increases the propensity of state natives to live in-state, while also extending in-state enrollment into the late twenties...

REVIEW
Amy McNeil, Ross Arena
In the last fifteen years, research on the link between health literacy (HL) and poor health outcomes has resulted in mixed results. Since 2004, concerted effort has been made to improve not only practitioner training, but also the HL of the United States population. And yet, to this day, only 12% of adults are considered health literate. Along with increased awareness of HL, creation of strategies and initiatives, such as shared decision, plain language, and decision aides, have improved patient-centered approaches to facilitating a person's ability to obtain and understand health information to the extent that they are able to affect a level of health autonomy; efforts have clearly fallen short given that during the same amount of time, the unhealthy living phenotype and chronic disease burden persists globally...

OBJECTIVE: Health websites are becoming important sources for cancer information. Lay users, patients and carers seek support for critical decisions, but they are prone to common biases when quantitative information is presented. Graphical representations of risk data can facilitate comprehension, and interactive visualizations are popular. This review summarizes the evidence on computer-supported graphs that present risk data and their effects on various measures. METHODS: The systematic literature search was conducted in several databases, including MEDLINE, EMBASE and CINAHL...

BACKGROUND: Flat pigmented facial lesions are difficult to diagnose even with dermatoscopy. It is controversial how additional information obtained by in vivo reflectance confocal microscopy (RCM) impacts the diagnosis and management. OBJECTIVE: To examine what in vivo reflectance confocal microscopy of flat pigmented facial lesions adds to clinical examination using dermatoscopy including digital dermatoscopic monitoring. METHODS: We prospectively collected 70 cases of flat pigmented facial lesions and recorded diagnoses and management decisions by experts based on direct clinical examination aided by dermatoscopy including digital dermatoscopic monitoring and by remote experts who reviewed the corresponding confocal images...

PURPOSE OF REVIEW: Patients reaching end-stage kidney disease face difficult decisions, including choosing among renal replacement therapies (RRTs). With an increasingly elderly and frail population, there is growing interest in conservative kidney management (CKM) as a viable alternative to dialysis. Shared decision-making (SDM) is a patient-centered approach to these decisions, in which choices are viewed within the explicitly discussed values and preferences of the patient. Patient decision aids (PDAs) are tools designed to facilitate these discussions...

PURPOSE OF REVIEW: This article intends to review biomarkers derived from blood, urine, and tissue that can aid in the diagnosis of prostate cancer (PCa). RECENT FINDINGS: PCa screening requires tools that complement prostate-specific antigen (PSA) with a higher specificity for clinically significant disease. Novel blood biomarkers, such as the Prostate Health Index (phi) and 4Kscore, utilize isoforms of PSA to more accurately predict high-grade PCa than traditional tools such as PSA and the percentage free-to-total PSA...

Zhi-Hui Zhang, Guang-Hong Yang
This paper provides a novel event-triggered fault detection (FD) scheme for discrete-time linear systems. First, an event-triggered interval observer is proposed to generate the upper and lower residuals by taking into account the influence of the disturbances and the event error. Second, the robustness of the residual interval against the disturbances and the fault sensitivity are improved by introducing l1 and H∞ performances. Third, dilated linear matrix inequalities are used to decouple the Lyapunov matrices from the system matrices...
