Jaden B Travnik, Patrick M Pilarski
Prosthetic devices have advanced in their capabilities and in the number and type of sensors included in their design. As the space of sensorimotor data available to a conventional or machine learning prosthetic control system increases in dimensionality and complexity, it becomes increasingly important that this data be represented in a useful and computationally efficient way. Well structured sensory data allows prosthetic control systems to make informed, appropriate control decisions. In this study, we explore the impact that increased sensorimotor information has on current machine learning prosthetic control approaches...

This paper presents the results of two surveys conducted with users of a functional upper extremity orthosis called the Wilmington Robotic EXoskeleton (WREX). The WREX is a passive anti-gravity arm orthosis that allows people with neuromuscular disabilities to move their arms in three dimensions. An online user survey with 55 patients was conducted to determine the benefits of the WREX. The survey asked 10 questions related to upper extremity function with and without the WREX as well as subjective impressions of the device...

Kinematic compatibility is of paramount importance in wearable robotic and exoskeleton design. Misalignments between exoskeletons and anatomical joints of the human body result in interaction forces which make wearing the exoskeleton uncomfortable and even dangerous for the human. In this paper we present a kinematically compatible design of an exoskeleton hip to reduce kinematic incompatibilities, so called macro- and micro-misalignments, between the human's and exoskeleton's joint axes, which are caused by inter-subject variability and articulation...

In the recent decades state of the art technologies appeared in many areas to assist older adults with disabilities. However, one very essential activity of daily life, the toileting remained without any relevant development. The iToilet project of the European Union focuses on the development of an intelligent and motorized toilet system to enable independent toilet use for older adults with disabilities. To begin the development, the user requirements of end-users were assessed by means of focus group interviews and questionnaires...

Kevin D Bui, Roshan Rai, Michelle J Johnson
In this study, we aim to explore ways to objectively assess cognitive deficits in the stroke and HIV/stroke populations, where cognitive and motor impairments can be hard to separate. Using an upper limb rehabilitation robot called the Haptic TheraDrive, we collect performance error scores and motor learning data on the impaired and unimpaired limb during a trajectory tracking task. We compare these data to clinical cognitive scores. The preliminary results suggest a possible relationship between unimpaired upper limb performance error and visuospatial/executive function cognitive domains, but more work needs to be done to further investigate this...

Upper limb rehabilitation training for Hemiplegie patients has been conducted mainly by human therapists. Training methods and conditions depend strongly on their experience because of the wide range of individual differences between patients. The force control and sensing functions of rehabilitation robots are expected to be used for the qualitative assessment of next-generation computational rehabilitation. In this study, we developed a simple exercise machine for upper limbs (SEMUL) using an electro-rheological fluid brake, as a safe brake-type robotic rehabilitation system...

The main challenges of designing devices for paraplegic walking can be summarized into three groups, stability and comfort, high efficiency or low energy consumption, dimensions and weight. A new economical device for people with paraplegia which tackles all problems of the three groups is introduced in this paper. The main idea of this device is based on HALO mechanism. HALO is compact passive medial hip joint orthosis with contralateral hip and ankle linkage, which keeps the feet always parallel to the ground and assists swinging the leg...

Wolfgang Greiter, Uwe Firzlaff
The auditory cortex is an essential center for sound localization. In echolocating bats, combination sensitive neurons tuned to specific delays between call emission and echo perception represent target distance. In many bats, these neurons are organized as a chronotopically organized map of echo delay. However, it is still unclear to what extend these neurons can process directional information and thereby form a three-dimensional representation of space. We investigated the representation of three-dimensional space in the auditory cortex of Phyllostomus discolor...

Daniel P Hinton, Helen Higson
The present research aims to more fully explore the issues of performance differences in higher education assessment, particularly in the context of a common measure taken to address them. The rationale for the study is that, while performance differences in written examinations are relatively well researched, few studies have examined the efficacy of anonymous marking in reducing these performance differences, particularly in modern student populations. By examining a large archive (N = 30674) of assessment data spanning a twelve-year period, the relationship between assessment marks and factors such as ethnic group, gender and socio-environmental background was investigated...

REVIEW
Ross Roberts, Tim Woodman
In this review, we examine the literature in relation to personality and performance. Much of the extant work in this area has focused on the role of the Big 5 traits (i.e., extraversion, conscientiousness, openness to experience, agreeableness, and neuroticism), at the expense of other personality variables that have a strong performance-focused rationale. Further, a focus on main effects has dominated the literature, without recourse to consider person×environment interactions. In this review we go beyond the Big 5 and consider the role of two personality traits, narcissism and alexithymia, in relation to performance...

Identification of new hits is one of the biggest challenges in drug discovery. Creating a library of well-characterized drug-like compounds is a key step in this process. Our group has developed an in-house chemical library called Medicinal and Biological Chemistry (MBC) library. This collection has been successfully used to start several medicinal chemistry programs and developed in an accumulation of more than thirty years of experience in drug design and discovery of new drugs for unmet diseases. It contains over 1,000 compounds, mainly heterocyclic scaffolds...

Purpose: To present the translated and linguistic and culturally adapted version of the Short self-regulation Questionnaire (SSRQ) for the Brazilian Portuguese and to check its applicability to patients with dysphonia. Methods: The SSRQ is a tool used to evaluate the ability to self-regulate behavior; it has 31 items and generates three scores: total index of individual self-regulation capacity and partial scores for goal setting and impulse control. Each item should be scored by means of a Likert-type 5-point scale; the total score ranges from 29 to 145 points...

REVIEW
Roz Shafran, Sophie D Bennett, Mhairi McKenzie Smith
There are strong calls from many national and international bodies for there to be a 'holistic' and integrated approach to the understanding and management of psychological and physical health needs. Such holistic approaches are characterized by the treatment of the whole person, taking into account mental and social factors, rather than just the symptoms of a disease. Holistic approaches can impact on mental and physical health and are cost-effective. Several psychological interventions have demonstrated efficacy in improving holistic health outcomes, for example Cognitive Behaviour Therapy, Behavioural Therapies and Problem Solving Therapies...

Unni Gopinathan, Trygve Ottersen
Universal health coverage (UHC) is high on the global health agenda, and priority setting is fundamental to the fair and efficient pursuit of this goal. In a recent editorial, Rob Baltussen and colleagues point to the need to go beyond evidence on cost-effectiveness and call for evidence-informed deliberative processes when setting priorities for UHC. Such processes are crucial at every step on the path to UHC, and hopefully we will see intensified efforts to develop and implement processes of this kind in the coming years...

Dennis Raphael Raphael
For over 35 years Ronald Labonté has been critically analyzing the state of health promotion in Canada and the world. In 1981, he identified the shortcomings of the groundbreaking Lalonde Report by warning of the seductive appeal of so-called lifestyle approaches to health. Since then, he has left a trail of critical work identifying the barriers to - and opportunities for -health promotion work. More recently, he has shown how the rise of economic globalization and acceptance of neo-liberal ideology has come to threaten the health of those in both developed and developing nations...

Oliver Razum, Judith Wenner, Kayvan Bozorgmehr
Recourse to a purported ideal of societal homogeneity has become common in the context of the refugee reception crisis - not only in Japan, as Leppold et al report, but also throughout Europe. Calls for societal homogeneity in Europe originate from populist movements as well as from some governments. Often, they go along with reduced social support for refugees and asylum seekers, for example in healthcare provision. The fundamental right to health is then reduced to a citizens' right, granted fully only to nationals...

Courtney McNamara
Labonté et al provide an insightful analysis of the Trans-Pacific Partnership (TPP) and its impact on a selection of important health determinants. Their work confirms concerns raised by previous analyses of leaked drafts and offers governments serious and timely reasons to carefully consider provisions of the agreement prior to moving forward with ratification. It also contributes more generally to a growing literature focused on identifying the health impacts of trade. This commentary uses the authors' analysis as a starting point to reflect on two interrelated issues relevant both for taking seriously one of the article's main recommendations and future work in the area of trade and health...

Alex R DeCasien, Scott A Williams, James P Higham
The social brain hypothesis posits that social complexity is the primary driver of primate cognitive complexity, and that social pressures ultimately led to the evolution of the large human brain. Although this idea has been supported by studies indicating positive relationships between relative brain and/or neocortex size and group size, reported effects of different social and mating systems are highly conflicting. Here, we use a much larger sample of primates, more recent phylogenies, and updated statistical techniques, to show that brain size is predicted by diet, rather than multiple measures of sociality, after controlling for body size and phylogeny...

OBJECTIVE: Acetaminophen (APAP) or paracetamol is a commonly encountered medicine in poisonings. We studied the changes in APAP related calls to the Finnish poison information centre (FPIC), and serious intoxications, involving hepatotoxicity or death in 2001-2014. These data were compared with paracetamol sales in Finland. METHODS: This is a retrospective analysis of the FPIC database calls, national cause of death registry, registries of liver transplantations and molecular adsorbent recycling system (MARS)-treated patients from Helsinki University Hospital together with the National Institute of Health and Welfare registry of patients hospitalized...
