Stroke survivors with acquired language deficits are commonly thought to reach a 'plateau' within a year of stroke onset, after which their residual language skills will remain stable. Nevertheless, there have been reports of patients who appear to recover over years. Here, we analysed longitudinal change in 28 left-hemisphere stroke patients, each more than a year post-stroke when first assessed-testing each patient's spoken object naming skills and acquiring structural brain scans twice. Some of the patients appeared to improve over time while others declined; both directions of change were associated with, and predictable given, structural adaptation in the intact right hemisphere of the brain...

This paper aims to analyze the healthcare coordination by Primary Health Care (PHC), with the backdrop of building a Health Care Network (RAS) in a region in the state of São Paulo, Brazil. We conducted a case study with qualitative and quantitative approaches, proceeding to the triangulation of data between the perception of managers and experience of users. We drew analysis realms and variables from the three pillars of healthcare coordination - informational, clinical and administrative/organizational. Stroke was the tracer event chosen and therapeutic itineraries were conducted with users and questionnaires applied to the managers...

In conversation, turn-taking is usually fluid, with next speakers taking their turn right after the end of the previous turn. Most, but not all, previous studies show that next speakers start to plan their turn early, if possible already during the incoming turn. The present study makes use of the list-completion paradigm (Barthel et al., 2016), analyzing speech onset latencies and eye-movements of participants in a task-oriented dialogue with a confederate. The measures are used to disentangle the contributions to the timing of turn-taking of early planning of content on the one hand and initiation of articulation as a reaction to the upcoming turn-end on the other hand...

HYPOTHESIS: Custom prostheses could be used to recreate the ossicular chain and improve hearing. BACKGROUND: Ossicular discontinuity or fixation occurs in 55% of cases of conductive hearing loss, with most cases involving the incus. Reconstruction has been achieved by a variety of methods; however, there has been little improvement in hearing outcomes in decades. METHODS: Precise measurements of anatomic dimensions, weight, and center of gravity were taken from 19 cadaveric incudes...

OBJECTIVE To evaluate the effects of exercise in an underwater treadmill (UWT) on forelimb biomechanics and articular histologic outcomes in horses with experimentally induced osteoarthritis of the middle carpal joint. ANIMALS 16 horses. PROCEDURES An osteochondral fragment was induced arthroscopically (day 0) in 1 middle carpal joint of each horse. Beginning on day 15, horses were assigned to exercise in a UWT or in the UWT without water (simulating controlled hand walking) at the same speed, frequency, and duration...

The acoustic realization of speech is constrained by the physical mechanisms by which it is produced. Yet for speech perception, the degree to which listeners utilize experience derived from speech production has long been debated. In the present study, we examined how sensorimotor adaptation during production may affect perception, and how this relationship may be reflected in early vs. late electrophysiological responses. Participants first performed a baseline speech production task, followed by a vowel categorization task during which EEG responses were recorded...

BACKGROUND: As persons of trust, community-based physicians providing survivorship care (e.g., general practitioners [GPs]) often serve as the primary contacts for cancer survivors disclosing distress. From the perspective of physicians providing survivorship care for cancer patients, this study explores (a) the accessibility, availability, and potential benefits of psycho-oncology services; (b) whether physicians themselves provide psychosocial support; and (c) predictors for impeded referrals of survivors to services...

James E Sabin
Moral distress is a major problem for nurses, other clinicians, and the health system itself. But if properly understood and responded to, it is also a promising guide for healthcare improvement. When individuals experience moral distress or burnout, their reports must be seen as crucial data requiring careful attention to the individuals and to the organization. Distress and burnout will often point to important opportunities for system improvements, which may in turn reduce the experience of distress. For this potential virtuous cycle to happen, individuals must be able to articulate their concerns without fear of retribution, and organizational leaders must be able to listen in an undefensive, improvement-oriented manner...

Integrative Data Analysis (IDA) encompasses a collection of methods for data synthesis that pools participant-level data across multiple studies. Compared with single-study analyses, IDA provides larger sample sizes, better representation of participant characteristics, and often increased statistical power. Many of the methods currently available for IDA have focused on examining developmental changes using longitudinal observational studies employing different measures across time and study. However, IDA can also be useful in synthesizing across multiple randomized clinical trials to improve our understanding of the comprehensive effectiveness of interventions, as well as mediators and moderators of those effects...

On March 15, 2017 the union cabinet approved the new National Health Policy. The next day a 28-page policy text and an accompanying 13-page situational analysis were placed in Parliament and in the public domain. To have, at all times, a health policy in place that shows a road map on how a nation would show "progressive realization" of health as a basic human right is an obligation under the International Covenant on Economic, Social and Cultural Rights. This is an international treaty adopted in 1976, to which India became a signatory in 1979, and this was one of the catalysts for the adoption of the first National Health Policy in 1 983...

Indigenous women are subjected to high rates of multiple forms of violence, including intimate partner violence (IPV), in the context of ongoing colonization and neo-colonization. Health promotion interventions for women who experience violence have not been tailored specifically for Indigenous women. Reclaiming Our Spirits (ROS) is a health promotion intervention designed for Indigenous women living in an urban context in Canada. In this paper, we describe the development of the intervention, results of a pilot study, and the revised subsequent intervention...

BACKGROUND: Ankle-foot orthosis moment resisting plantarflexion has systematic effects on ankle and knee joint motion in individuals post-stroke. However, it is not known how much ankle-foot orthosis moment is generated to regulate their motion. The aim of this study was to quantify the contribution of an articulated ankle-foot orthosis moment to regulate ankle and knee joint motion during gait in individuals post-stroke. METHODS: Gait data were collected from 10 individuals post-stroke using a Bertec split-belt instrumented treadmill and a Vicon 3-dimensional motion analysis system...

BACKGROUND: Children often have difficulty accessing subspecialty care, and telemedicine may improve access to subspecialty care, but information is lacking on how best to implement telemedicine programs to maximize acceptance and, ultimately, maximize impact for patients and their families. METHODS AND MATERIALS: To understand how subspecialty telemedicine is perceived and to identify design elements with the potential to improve telemedicine uptake and impact, we conducted and analyzed semi-structured interviews with 21 informants, including parents and caregivers of children with subspecialty care needs and adolescent and young adult patients with subspecialty care needs...

Shira Kramer, Colin L Soskolne
PURPOSE OF REVIEW: This review integrates historical developments and key events in bringing ethics into epidemiology in general and into environmental epidemiology in particular. The goal is to provide context for and discern among the various approaches and motivations that drive the need for ethical conduct in support of the public interest. RECENT FINDINGS: The need for ethics guidelines in epidemiology is different from developments in other biomedical-related fields by virtue of its focus on populations rather than on individuals...

Ionic substitution can affect essential physicochemical properties leading to a specific biological behavior upon implantation. Therefore it has been proposed as a tool to increase the biological efficiency of calcium phosphate based materials. In the following study we have evaluated the contribution of an important cation in nature, Mg2+, into the structure of previously studied biocompatible and biodegradable hydroxyapatite (HA) nano-rods and its subsequent effect on its chemical, morphology and bone mimetic articulation...

We have recently shown in Finnish speakers that articulation of certain vowels and consonants has a systematic influence on simultaneous grasp actions as well as on forward and backward hand movements. Here we studied whether these effects generalize to another language, namely Czech. We reasoned that if the results generalized to another language environment, it would suggest that the effects arise through other processes than language-dependent semantic associations. Rather, the effects would be likely to arise through language-independent interactions between processes that plan articulatory gestures and hand movements...

We investigated the relationship between imaging variables for two language/speech-motor tracts and speech fluency variables in 10 minimally verbal (MV) children with autism. Specifically, we tested whether measures of white matter integrity-fractional anisotropy (FA) of the arcuate fasciculus (AF) and frontal aslant tract (FAT)-were related to change in percent syllable-initial consonants correct, percent items responded to, and percent syllable insertion errors (from best baseline to post 25 treatment sessions)...

We report on the pioneering discovery of Devonian fish remains in the Paraná Basin, which represents the southernmost record of fishes from that period in mainland South America. The material comes from an outcrop at the lower portion of the São Domingos Formation, within Sequence C of the Paraná-Apucarana sub-basin in Tibagi, State of Paraná. Marine invertebrates are abundant in the same strata. The dark colored fish remains were collected in situ and represent natural moulds of partially articulated shark fin rays (radials)...
