Sudden Complex Hallucinations in a 14-Year-Old Girl: Schizophrenia Spectrum Disorders Versus Dissociative Disorders-The Influence of Early Life Exper…
2020
A 14-year-old girl is taken to the pediatric emergency department (ED) by her parents because of sudden complex hallucinations.She shows moderate intellectual disability without a peculiar phenotype already evaluated by neuropediatrics (normal comparative genomic hybridization array and brain magnetic resonance imaging) and most likely related to affective deprivation at the orphanage. Adopted at 20 months from China, her parents reported that on arrival she had scars, allegedly from being tied to a chair for a long time, and that although she was able to stand, she could not walk. At 22 months, she had experienced several episodes of loss of consciousness with rigidity that were attributed…
Snapshot Spectral Imaging
2018
This chapter describes an application of the spline-based wavelet frames to the spectral imaging. It presents a method that enables to convert a regular digital camera into a snapshot spectral imager by equipping the camera with a dispersive diffuser and with a compressed sensing-based algorithm for digital processing. The method relies on the assumption that typical images can be sparsely represented in the frame domain. The solution is found from the constrained \(l_{1}\) minimization of a functional by Bregman iterations. Results of optical experiments are reported. The chapter is based on the paper (Golub et al., Appl. Opt. 55, 432–443, (2016), [11]).
Effects of a Vibro-Tactile P300 Based Brain-Computer Interface on the Coma Recovery Scale-Revised in Patients With Disorders of Consciousness
2020
Persons diagnosed with disorders of consciousness (DOC) typically suffer from motor and cognitive disabilities. Recent research has shown that non-invasive brain-computer interface (BCI) technology could help assess these patients’ cognitive functions and command following abilities. 20 DOC patients participated in the study and performed 10 vibro-tactile P300 BCI sessions over 10 days with 8–12 runs each day. Vibrotactile tactors were placed on the each patient’s left and right wrists and one foot. Patients were instructed, via earbuds, to concentrate and silently count vibrotactile pulses on either their left or right wrist that presented a target stimulus and to ignore …
Effects of rectilinear acceleration and optokinetic and caloric stimulations in space.
1984
During the flight of Spacelab 1 the crew performed a number of experiments to explore changes in vestibular function and visual-vestibular interactions on exposure to microgravity. Measurements were made on the threshold for detection of linear oscillation, vestibulo-ocular reflexes elicited by angular and linear movements, oculomotor and posture responses to optokinetic stimulations, and responses to caloric stimulation. Tests were also conducted on the ground, during the 4 months before and on days 1 to 6 after flight. The most significant result was that caloric mystagmus of the same direction as on the earth could also be evoked in the weightless environment.
European vestibular experiments on the Spacelab-1 mission: 1. Overview.
1986
During the flight of Spacelab-1 a series of vestibular experiments was performed on the crew by a group of European investigators. Control experiments were carried out on the same subjects pre- and postflight. The tests included caloric stimulation of the ears, threshold measurements of response to linear acceleration, motion sickness provocative stimuli, vestibulo-ocular reflexes during linear and angular stimulation, estimation of the subjective vertical (luminous line measurements) and static ocular counterrotation at various tilt angles. The caloric experiment proved the existence of a nonthermoconvective mechanism of caloric nystagmus in space. Most of the other test results point to a…
Coaches’ Health Promotion Activity and Substance Use in Youth Sports
2017
There is an increasing amount of evidence suggesting youth sports clubs are an important setting for health promotion. Adolescents in sport club settings can benefit from exposures of positive and negative consequences to health. To better understand the sport club context and coaches’ health promotion activity in substance use prevention, this study compares sport club members with non-members aged between 14–16 years old on their experience and use of alcohol, smoking and snuff and coaches’ health promotion activity on substances. Methods: Adolescents (n = 671) from sports clubs and from matched schools (n = 1442) were recruited in this study. Multiple binary logistic regressions were per…
Rapid Assessment of COVID-19 Screening Program for Travelers in Iran: A Qualitative Study
2022
AbstractObjective:Coronavirus disease 2019 (COVID-19) screening stations set up by Iranian Red Crescent Society have been available for 17 d with the aim of identifying and treating people with coronavirus, reducing road trips, and sensitizing people to the problem. This study aims to investigate the challenges of the procedure.Methods:A qualitative study was used to find the challenges of the COVID-19 screening centers. Volunteers, branch managers, and headquarter managers of the Iranian Red Crescent Society participated in this study applying snowball sampling. Data were collected by means of in-depth semi-structured telephone interviews in April 2020 after completion of the fever screeni…
Nutritional self-care among a group of older home-living people in rural Southern Norway
2015
Bjørg Dale, Ulrika SöderhamnCentre for Caring Research – Southern Norway, Faculty of Health and Sport Sciences, University of Agder, Grimstad, NorwayBackground: Older home-living people are an at-risk group for undernutrition, particularly those who are living alone. Lack of knowledge about healthy dietary habits, altered taste sensation, and declined health status are shown to be some of the factors related to undernutrition. The aims of this study were to explore how a small group of older people in Southern Norway perceived their nutritional self-care.Methods: An exploratory qualitative approach, combined with a simple self-report questionnaire, was used. Fi…
Relationship of subjective helplessness and pain perception after electric skin stimuli
2000
Objective and subjective controllability of painful stimuli are important factors in pain perception. The present study investigated direct and indirect effects of uncontrollability on perceived pain intensity in humans. Forty-eight healthy male volunteers participated in a laboratory experiment using a reaction time paradigm to induce controllable or uncontrollable feedback conditions in two randomly selected groups. Under controllable conditions, unpleasant electric skin shocks were applied, only when the actual time exceeded an individual threshold; under uncontrollable conditions, skin shocks were applied randomly using a yoked control design. Subjective helplessness, perceived pain int…
Neural Responses to Musical Rhythm in Chinese Children With Reading Difficulties
2020
The perception of the musical rhythm has been suggested as one of the predicting factors for reading abilities. Several studies have demonstrated that children with reading difficulties (RD) show reduced neural sensitivity in musical rhythm perception. Despite this prior evidence, the association between music and reading in Chinese is still controversial. In the present study, we sought to answer the question of whether the musical rhythm perception of Chinese children with RD is intact or not, providing further clues on how reading and music might be interlinked across languages. Oddball paradigm was adapted for testing the difference of musical rhythm perception, including predictable an…
