Research in myoelectric pattern recognition (MPR) for the prediction of motor volition has primarily focused on the upper limbs. Recent studies in the lower limbs have mainly concentrated on prosthetic control, while MPR for lower limb rehabilitation purposes has received little attention. In this work we investigated the viability of a MPR system for the prediction of four degrees of freedom controlled in a near natural or physiologically appropriate fashion. We explored three different electrode configurations for acquiring electromyographic (EMG) signals: two targeted (bipolar and monopolar) and one untargeted (electrodes equally spaced axially)...

Fetal heart rate (fHR) monitoring is usually performed by Doppler ultrasound (US) techniques. For reliable fHR measurements it is required that the fetal heart is located within the US beam. In clinical practice, clinicians palpate the maternal abdomen to identify the fetal presentation and then the US transducer is fixated on the maternal abdomen where the best fHR signal can be obtained. Finding the optimal transducer position is done by listening to the strength of the Doppler audio output and relying on a signal quality indicator of the cardiotocographic (CTG) measurement system...

There is a discontinuity in published electromechanical delays (EMD) in upper-limb muscles and the state-of-the-art in modelling end-point force from electromyographic signals collected from one or more muscles. Published values are typically in the range of 10 to 30ms, depending on the nature of the contraction. In published literature where the EMG-force relationship is modelled, generally a delay of 100ms or more is induced during linear enveloping to match the EMD. The implications of EMD on end-point force prediction were considered using inter-session end-point force modelling with a support-vector-regression model...

Eye blinks artifacts correction in the EEG signal is a best practice in many applications. Nowadays, different approaches can be used to overcome such an issue: the most used methods are based on regression techniques and Independent Component Analysis. It is not clear which is the best performing method, thus the choice of which method to adopt depends on the specific application, on the basis of the method limitations. In fact, on one hand the regression-based methods require at least one EOG channel, and are affected by the mutual contamination between EEG and EOG signals...

Independent Component Analysis (ICA) is a powerful statistical tool capable of separating multivariate scalp electrical signals into their additive independent or source components, specifically EEG or electroencephalogram and artifacts. Although ICA is a widely accepted EEG signal processing technique, classification of the recovered independent components (ICs) is still flawed, as current practice still requires subjective human decisions. Here we build on the results from Fitzgibbon et al. [1] to compare three measures and three ICA algorithms...

BACKGROUND: Opioid use, abuse, and adverse consequences, including death, have escalated at an alarming rate since the 1990s. In an attempt to control opioid abuse, numerous regulations and guidelines for responsible opioid prescribing have been developed by various organizations. However, the US opioid epidemic is continuing and drug dose deaths tripled during 1999 to 2015. Recent data show a continuing increase in deaths due to natural and semisynthetic opioids, a decline in methadone deaths, and an explosive increase in the rates of deaths involving other opioids, specifically heroin and illicit synthetic fentanyl...

We present an urban runoff model designed for stormwater managers to quantify runoff reduction benefits of mitigation actions that has lower input data and user expertise requirements than most commonly used models. The stormwater tool to estimate load reductions (TELR) employs a semi-distributed approach, where landscape characteristics and process representation are spatially-lumped within urban catchments on the order of 100 acres (40 ha). Hydrologic computations use a set of metrics that describe a 30-year rainfall distribution, combined with well-tested algorithms for rainfall-runoff transformation and routing to generate average annual runoff estimates for each catchment...

Measurements of health indicators are rarely available for every population and period of interest, and available data may not be comparable. The Guidelines for Accurate and Transparent Health Estimates Reporting (GATHER) define best reporting practices for studies that calculate health estimates for multiple populations (in time or space) using multiple information sources. Health estimates that fall within the scope of GATHER include all quantitative population-level estimates (including global, regional, national, or subnational estimates) of health indicators, including indicators of health status, incidence and prevalence of diseases, injuries, and disability and functioning; and indicators of health determinants, including health behaviours and health exposures...

The NCLEX-RN® was adopted by Canadian regulators in 2011 as the test which entry-level nurses must pass in order to be certified to practice. As part of their justification for adopting the exam, the Canadian regulators pointed to two studies conducted by the National Council of State Boards of Nursing (NCSBN). These studies aimed to determine the applicability of the NCLEX-RN® test plan to the Canadian testing population (NCSBN, 2014),with the NCLEX-RN® providing "a fair, valid, and psychometrically sound measurement" of nursing competencies of entry-level RNs in Ontario, Canada (NCSBN, 2012 , p...

PURPOSE: The medical education community is rapidly accepting the use of entrustable professional activities (EPAs) as a means of assessing residents. Stakeholder engagement is advised in developing EPAs, but no studies have investigated the role of patient input. In this qualitative study, the authors investigated what patient input may add to designing a patient-centered EPA. METHOD: The authors chose "management of acute low back pain (LBP)" as a common, important clinical task on which to base the patient-centered EPA...

PURPOSE: Community-based faculty play a large role in training medical students nationwide and require faculty development. The authors hypothesized that positive relationships exist between clerkships paying preceptors and requiring faculty development, and between protected clerkship directors' time and delivering face-to-face preceptor training, as well as with the number or length of community-based preceptor visits. Through under standing the quantity, delivery methods, barriers, and institutional support for faculty development provided to community-based preceptors teaching in family medicine clerkships, best practices can be developed...

OBJECTIVE: We present the first generic theoretical formulation of the co-adaptive learning problem and give a simple example of two interacting linear learning systems, a human and a machine. APPROACH: After the description of the training protocol of the two learning systems, we define a simple linear model where the two learning agents are coupled by a joint loss function. The simplicity of the model allows us to find learning rules for both human and machine that permit computing theoretical simulations...

PURPOSE: Tumor genomic testing has become widely available in many clinical settings. However, we do not yet understand how to best harness the information yielded from this testing. We retrospectively investigated the clinical courses of 24 patients who underwent tumor genomic testing to determine whether targeted therapy is associated with improved progression free survival (PFS) compared to standard therapy. METHODS: The patient population comprised metastatic breast cancer patients who underwent tumor genomic testing (testing biopsy specimens of primary or metastatic lesions for 50 commonly mutated genes) at our institution between September 1, 2010 and June 1, 2015...

BACKGROUND: Rheumatoid arthritis (RA) is a chronic inflammatory arthritis requiring long-term treatment with regular monitoring by a rheumatologist to achieve good health outcomes. Since people with RA may wish to monitor their own disease activity with a smartphone app, it is important to understand the functions and quality of apps for this purpose. OBJECTIVE: The aim of our study was to assess the features and quality of apps to assist people to monitor their RA disease activity by (1) summarizing the available apps, particularly the instruments used for measurement of RA disease activity; (2) comparing the app features with American College of Rheumatology and European League against Rheumatism (ACR and EULAR) guidelines for monitoring of RA disease activity; and (3) rating app quality with the Mobile App Rating Scale (MARS)...

The concept of value in radiology has been strongly advocated in recent years as a means of advancing patient care and decreasing waste. This article explores the concept of value creation in radiology and offers a framework for how radiology practices can create value according to the needs of their referring clinicians. Value only exists in the eyes of a customer. We propose that the primary purpose of diagnostic radiology is to answer clinical questions using medical imaging to help guide management of patient care...

Head motion during fMRI scans negatively impacts data quality, and as post-acquisition techniques for addressing motion become increasingly stringent, data retention decreases. Studies conducted with adult participants suggest that movement acts as a relatively stable, heritable phenotype that serves as a marker for other genetically influenced phenotypes. Whether these patterns extend downward to childhood has critical implications for the interpretation and generalizability of fMRI data acquired from children...
