OBJECTIVEAneurysm growth is considered predictive of future rupture of intracranial aneurysms. However, how accurately neuroradiologists can reliably detect incremental aneurysm growth using clinical MRI is still unknown. The purpose of this study was to assess the agreement rate of detecting aneurysm enlargement employing generally used MRI modalities.METHODSThree silicone flow phantom models, each with 8 aneurysms of various sizes at different sites, were used in this study. The aneurysm models were identical except for an incremental increase in the sizes of the 8 aneurysms, which ranged from 0.4 mm to 2 mm. The phantoms were imaged on 1.5-T and 3-T MRI units with both time-of-flight (TOF) and contrast-enhanced MR angiography. Three independent expert neuroradiologists measured the aneurysms in a blinded manner using different measurement approaches. The individual and agreement detection rates of aneurysm enlargement among the 3 experts were calculated.RESULTSThe mean detection rate of any increase in any aneurysmal dimension was 95.7%. The detection rates of the 3 observers (observers A, B, and C) were 98.0%, 96.6%, and 92.7%, respectively (p = 0.22). The detection rates of each MRI modality were 91.3% using 1.5-T TOF, 97.2% using 1.5-T with Gd, 95.8% using 3.0-T TOF, and 97.2% using 3.0-T with Gd (p = 0.31). On the other hand, the mean detection rate for aneurysm enlargement was 54.8%. Specifically, the detection rates of observers A, B, and C were 49.0%, 46.1%, and 66.7%, respectively (p = 0.009). As the incremental enlargement value increased, the detection rate for aneurysm enlargement increased. The use of 1.5-T Gd improved the detection rate for small incremental enlargement (e.g., 0.4–1 mm) of the aneurysm (p = 0.04). The location of the aneurysm also affected the detection rate for aneurysm enlargement (p < 0.0001).CONCLUSIONSThe detection rate and interobserver agreement were very high for aneurysm enlargement of 0.4–2 mm. The detection rate for at least 1 increase in any aneurysm dimension did not depend on the choice of MRI modality or measurement protocol. Use of Gd improved the accuracy of measurement. Aneurysm location may influence the accuracy of detecting enlargement.

Published: March 2018

Background: Preliminary evidence showed additional effects of anodal transcranial direct current stimulation over the damaged cerebral hemisphere combined with cathodal transcutaneous spinal direct current stimulation during robot-assisted gait training in chronic stroke patients. This is consistent with the neural organization of locomotion involving cortical and spinal control. The cerebellum is crucial for locomotor control, in particular for avoidance of obstacles, and adaptation to novel conditions during walking. Despite its key role in gait control, to date the effects of transcranial direct current stimulation of the cerebellum have not been investigated on brain stroke patients treated with robot-assisted gait training. Objective: To evaluate the effects of cerebellar transcranial direct current stimulation combined with transcutaneous spinal direct current stimulation on robot-assisted gait training in patients with chronic brain stroke. Methods: After balanced randomization, 20 chronic stroke patients received ten, 20-minute robot-assisted gait training sessions (five days a week, for two consecutive weeks) combined with central nervous system stimulation. Group 1 underwent on-line cathodal transcranial direct current stimulation over the contralesional cerebellar hemisphere + cathodal transcutaneous spinal direct current stimulation. Group 2 received on-line anodal transcranial direct current stimulation over the damaged cerebral hemisphere + cathodal transcutaneous spinal direct current stimulation. The primary outcome was the 6-minute walk test performed before, after, and at follow-up at 2 and 4 weeks post-treatment. Results: The significant differences in the 6-minute walk test noted between groups at the first post-treatment evaluation ( p = 0.041) were not maintained at either the 2-week ( P = 0.650) or the 4-week ( P = 0.545) follow-up evaluations. Conclusion: Our preliminary findings support the hypothesis that cathodal transcranial direct current stimulation over the contralesional cerebellar hemisphere in combination with cathodal transcutaneous spinal direct current stimulation might be useful to boost the effects of robot-assisted gait training in chronic brain stroke patients with walking impairment.
Sensorimotor integration in chronic stroke: Baseline differences and response to sensory training
Authors: Brown Katlyn E. , Neva Jason L. , Feldman Samantha J. , Staines W. Richard , Boyd Lara A. 
Published: March 2018

Background: The integration of somatosensory information from the environment into the motor cortex to inform movement is essential for motor function. As motor deficits commonly persist into the chronic phase of stroke recovery, it is important to understand potential contributing factors to these deficits, as well as their relationship with motor function. To date the impact of chronic stroke on sensorimotor integration has not been thoroughly investigated. Objectives: The current study aimed to comprehensively examine the influence of chronic stroke on sensorimotor integration, and determine whether sensorimotor integration can be modified with an intervention. Further, it determined the relationship between neurophysiological measures of sensorimotor integration and motor deficits post-stroke. Methods: Fourteen individuals with chronic stroke and twelve older healthy controls participated. Motor impairment and function were quantified in individuals with chronic stroke. Baseline neurophysiology was assessed using nerve-based measures (short- and long-latency afferent inhibition, afferent facilitation) and vibration-based measures of sensorimotor integration, which paired vibration with single and paired-pulse TMS techniques. Neurophysiological assessment was performed before and after a vibration-based sensory training paradigm to assess changes within these circuits. Results: Vibration-based, but not nerve-based measures of sensorimotor integration were different in individuals with chronic stroke, as compared to older healthy controls, suggesting that stroke differentially impacts integration of specific types of somatosensory information. Sensorimotor integration was behaviourally relevant in that it related to both motor function and impairment post-stroke. Finally, sensory training modulated sensorimotor integration in individuals with chronic stroke and controls. Conclusion: Sensorimotor integration is differentially impacted by chronic stroke based on the type of afferent feedback. However, both nerve-based and vibration-based measures relate to motor impairment and function in individuals with chronic stroke.

Published: March 2018

Background: Effective human-robot interactions in rehabilitation necessitates an understanding of how these should be tailored to the needs of the human. We report on a robotic system developed as a partner on a 3-D everyday task, using a gamified approach. Objectives: To: (1) design and test a prototype system, to be ultimately used for upper-limb rehabilitation; (2) evaluate how age affects the response to such a robotic system; and (3) identify whether the robot’s physical embodiment is an important aspect in motivating users to complete a set of repetitive tasks. Methods: 62 healthy participants, young (<30 yo) and old (>60 yo), played a 3D tic-tac-toe game against an embodied (a robotic arm) and a non-embodied (a computer-controlled lighting system) partner. To win, participants had to place three cups in sequence on a physical 3D grid. Cup picking-and-placing was chosen as a functional task that is often practiced in post-stroke rehabilitation. Movement of the participants was recorded using a Kinect camera. Results: The timing of the participants’ movement was primed by the response time of the system: participants moved slower when playing with the slower embodied system ( p = 0.006). The majority of participants preferred the robot over the computer-controlled system. Slower response time of the robot compared to the computer-controlled one only affected the young group’s motivation to continue playing. Conclusion: We demonstrated the feasibility of the system to encourage the performance of repetitive 3D functional movements, and track these movements. Young and old participants preferred to interact with the robot, compared with the non-embodied system. We contribute to the growing knowledge concerning personalized human-robot interactions by (1) demonstrating the priming of the human movement by the robotic movement – an important design feature, and (2) identifying response-speed as a design variable, the importance of which depends on the age of the user.
Exploring the Limits of AGN Feedback: Black Holes and the Star Formation Histories of Low-mass Galaxies
Authors: Martín-Navarro I. , Mezcua M. 
Published: March 2018

Abstract
Energy feedback, either from active galactic nuclei (AGNs) or from supernovae, is required to understand galaxy formation within a Λ-cold dark matter cosmology. We study a sample of 127 low-mass galaxies, comparing their stellar population properties to the mass of the central supermassive black hole, in order to investigate the effect of AGN feedback. We find a loose coupling between star formation history and black hole mass, which seems to suggest that AGN activity does not dominate baryonic cooling in low-mass galaxies. We also find that a break in the

, remarkably similar to

. Our results are in agreement with a bi-modal star formation process where the AGN-dominated feedback of high-mass galaxies transitions toward a supernovae-driven regime in low-mass systems, as suggested by numerical simulations.
Penumbral Waves Driving Solar Fan-shaped Chromospheric Jets

Published: March 2018

Abstract
We use Hα imaging spectroscopy taken via the Swedish 1 m Solar Telescope to investigate the occurrence of fan-shaped jets at the solar limb. We show evidence for near-simultaneous photospheric reconnection at a sunspot edge leading to the jets appearance, with upward velocities of 30 km s−1, and extensions up to 8 Mm. The brightening at the base of the jets appears recurrent, with a periodicity matching that of the nearby sunspot penumbra, implying running penumbral waves could be the driver of the jets. The jets’ constant extension velocity implies that a driver counteracting solar gravity exists, possibly as a result of the recurrent reconnection erupting material into the chromosphere. These jets also show signatures in higher temperature lines captured from the Solar Dynamics Observatory, indicating a very hot jet front, leaving behind optically thick cool plasma in its wake.

Authors: Shafik Shaheen Mohamed , Lolah Mohamed M. , Piñero David P. 
Published: March 2018

PURPOSE:
To evaluate the clinical results of epitheliumoff corneal cross-linking (CXL) during a 7-year follow-up.

METHODS:
This retrospective, non-randomized, single-center interventional study enrolled 34 consecutive eyes of 24 patients with progressive keratoconus undergoing CXL surgery with epithelium removal. Visual, refractive, corneal topographic, pachymetric, and anterior segment changes were evaluated at 1, 3, and 7 years after surgery.

RESULTS:

Significant reduction of refraction was observed at 1 year postoperatively (
P
≤ .006), with an additional significant reduction between the 1- and 3-year postoperative visits (
P
≤ .002) and no significant changes afterward (
P
≥ .156). Regarding corrected distance visual acuity (CDVA), a significant improvement was detected at 1 year after surgery (
P
< .001), with an additional improvement between 1 and 3 years postoperatively (
P
= .001), and no significant changes at the end of the follow-up (
P
= .518). Significant corneal flattening was observed at 1, 3, and 7 years after surgery (
P
≤ .041). Likewise, a significant central thinning was observed at 1 year postoperatively (
P
< .001), with no significant changes afterward (
P
≥ .112). Anterior maximum elevation only changed significantly between 1 and 3 years after surgery (
P
= .002), whereas the posterior maximum elevation changed significantly at all time points of the follow-up (
P
≤ .034). No significant changes with surgery in anterior segment volume (
P
≥ .377) and anterior chamber depth (
P
≥ .142) were detected.

CONCLUSIONS:
The effect of epithelium-off CXL in progressive keratoconus is maintained 7 years after surgery. Long-term corneal changes after this procedure may be influenced by an age-related corneal stiffening process.

People have access to implicit self-esteem unless they do not apply an ego defence
Authors: Fila-Jankowska Aleksandra Katarzyna 
Published: March 2018

BackgroundEarly definitions of implicit self-esteem (ISE) assumed its unconscious character. Although researchers have shown ways to achieve consistency between explicit and implicit self-esteem measures, no one has demonstrated that people may be aware of their ISE.Participants and procedureIn the experiment with 85 participants aged from 19 to 45 years a “lie detector” procedure was used to overcome the self-enhancement bias. The definition of ISE, given to participants, referred to the phenomenon, manifested in popular ISE measures.ResultsIn participants who were convinced that they were being assessed in the presence of a lie detector, a significant correlation between referred and actual ISE was shown. Individuals characterised by defensive high self-esteem in natural conditions were less accurate in ISE estimation than those with secure high self-esteem.ConclusionsThe results, demonstrating people’s access to their implicit self-esteem, may have important implications for clinical, well-being, self-acceptance, or educational issues.
Meaning in life in cancer patients: relationships with illness perception and global meaning changes
Authors: Krok Dariusz , Telka Ewa 
Published: March 2018

BackgroundMeaning in life seems to play an important role at various stages of coping in cancer patients. It can influence the ways in which cancer patients perceive their illness and potential changes in beliefs and goals. The main aim of the current study is to examine how two dimensions – presence of and search for meaning – are related to illness perception and global meaning changes.Participants and procedureThe research was conducted among 231 cancer patients (136 women and 95 men), between 27 and 86 years of age (M = 56.73, SD = 12.64). They were diagnosed with gastrointestinal cancer (stomach, colon, pancreas, liver, large intestine). The following research methods were used: the Meaning in Life Questionnaire, the Appraisal of the Disease Scale, and the Scale of Changes in Beliefs and Goals.ResultsPresence of meaning was associated with illness perceptions, changes of beliefs, and changes of goals. In contrast, there were no statistically significant relations between search for meaning and illness perception. The cluster analysis showed that the patients who were in presence style less negatively perceived their illness than those in presence and search style. The former also experienced fewer disruptions in important beliefs and goals than the latter. In addition, the patients in presence style were characterized by less negative illness perceptions and fewer disruptions in beliefs and goals than their compeers in indifferent style.ConclusionsHaving meaning in life is related to a more satisfactory image of the illness and fewer violations in the belief and goal system. Searching for meaning, even though accompanied by presence of meaning, is rather detrimental to illness perception and changes in beliefs and goals. The awareness of having a purpose and overarching aim in life helps cancer patients to interpret and organize their stressful experiences, and perceive the illness from a less negative perspective.
An exploratory examination of mindfulness, self-compassion, and mindful eating in relation to motivations to eat palatable foods and BMI
Authors: Mantzios Michail , Egan Helen 
Published: March 2018

BackgroundPreliminary findings suggest that mindfulness and self-compassion training are associated with enhanced weight regulation. However, the associations between these traits and body mass index (BMI) are mixed.Participants and procedureIn a cross-sectional investigation, university students (n = 183) were asked to fill in questionnaires on mindfulness, self-compassion, mindful eating, and motivations to eat palatable foods.ResultsThe results suggest that mindfulness, self-compassion and mindful eating related negatively to motivations to eat palatable foods. Mindful eating displayed the most significant relationship. Further investigations showed that some subscales of self-compassion, mindfulness and mindful eating related to motivations to eat palatable foods and BMI more significantly. The ability to draw more and better conclusions by investigating the relationship of subscales to health behaviors and outcomes, especially with self-compassion, has been noted in previous rationales and theories. The notable relationships were (a) the enhancement subscale of the motivations to eat palatable foods, which appeared to relate positively to self-judgment, isolation, and over-identification, while (b) the coping subscale related to all subscales within the self-compassion scale.ConclusionsThe current findings support different lines of research that suggest that mindful eating, mindfulness and/or self-compassion support weight regulation. Mindfulness practices could potentially add the right motives to eat palatable foods (such as being motivated to eat when people are hungry), and potentially eat less of the foods that lead to weight dysregulation. The findings are discussed and suggested paths for further research are recommended.
Does belief in free will make us feel good and satisfied?
Authors: Kondratowicz-Nowak Blanka Beata , Zawadzka Anna Maria 
Published: March 2018

BackgroundRecent studies have shown that maintaining a strong belief in free will may be associated with well-being at the workplace (Stillman, Baumeister, Vohs, Lambert, Fincham, & Brawer, 2010), more frequent attainment of pursued goals and emotional stability (Stillman, Baumeister, & Mele, 2011).Participants and procedureTwo studies were conducted to investigate to what extent belief in free will (as opposed to belief in determinism) may be a good predictor of subjective well-being and ill-being (poor health condition). Study 1 investigated a sample of employees (N = 214): 106 women and 108 men. The second research was conducted among 436 students: 236 women and 198 men.ResultsThe results of study 1 showed that those who believe in free will are satisfied with their lives and feel healthy. The results of study 2 showed that those who believe in free will feel better (have more positive emotions) and are more satisfied with their lives than those who believe in determinism.ConclusionsBelief in free will has the potential for improving subjective well-being and belief in determinism (fate) lowers subjective well-being. What is more, the current study has also confirmed the results obtained by other researchers (Paulhus & Carey, 1994, Carey & Paulhus, 2013). The reliability of the free will subscale was replicated. Also, we confirmed a positive correlation between belief in free will and unpredictability, and between fatalistic determinism and unpredictability. The results of the present research proved that there is a need to develop and to promote belief in free will in societies and social policies because it can increase well-being.
