To provide appropriate solutions for problematic smartphone use, we need to first understand its types. This study aimed to identify types of problematic smartphone use based on psychiatric symptoms, using the decision tree method. We recruited 5,372 smartphone users from online surveys conducted between February 3 and February 22, 2016. Based on scores on the Korean Smartphone Addiction Proneness Scale for Adults (S-Scale), 974 smartphone users were assigned to the smartphone-dependent group and 4398 users were assigned to the normal group...

BACKGROUND: Interoception may contribute to substance use disorder as it relates to the body's experience of substance use or withdrawal. However, only a few studies have directly investigated associations between interoception and alcohol use. The objective of this study was to compare individuals with alcohol use disorder (AUD) and healthy controls on interoceptive sensibility and accuracy. METHODS: The sample was comprised of two groups: individuals meeting criteria for AUD (N = 114) and healthy controls (N = 110) not meeting criteria for AUD...

BACKGROUND: Small airways dysfunction (SAD) is well recognised in asthma, yet its role in the severity and control of asthma is unclear. This study aimed to assess which combination of biomarkers, physiological tests, and imaging markers best measure the presence and extent of SAD in patients with asthma. METHODS: In this baseline assessment of a multinational prospective cohort study (the Assessment of Small Airways Involvement in Asthma [ATLANTIS] study), we recruited participants with and without asthma (defined as Global Initiative for Asthma severity stages 1-5) from general practices, the databases of chest physicians, and advertisements at 29 centres across nine countries (Brazil, China, Germany, Italy, Spain, the Netherlands, the UK, the USA, and Canada)...

Linear and nonlinear impairments severely limit the transmission performance of high-speed visible light communication systems. Neural network-based equalizers have been applied to optical communication systems, which enables significantly improved system performance, such as transmission data rate and distance. In this paper, a memory-controlled deep long short-term memory (LSTM) neural network post-equalizer is proposed to mitigate both linear and nonlinear impairments in pulse amplitude modulation (PAM) based visible light communication (VLC) systems...

Background: Childhood maltreatment, such as severe emotional, physical, and sexual abuse and neglect, has been linked to impulse control problems and dysfunctional emotional coping. In borderline personality disorder (BPD), a history of childhood maltreatment may worsen difficulties in emotion regulation, which may in turn give rise to impulsive behaviours. The aim of this self-report study was to investigate associations between childhood maltreatment severity, emotion regulation difficulties, and impulsivity in women with BPD compared to healthy and clinical controls...

Electroencephalography (EEG) is an effective noninvasive measurement method to infer user intent in braincomputer interface (BCI) systems for control and communication, however these systems often lack sufficient accuracy and speed due to low separability of class-conditional EEG feature distributions. Many factors impact system performance, including inadequate training datasets and models' ignorance of the temporal dependency of brain responses to serial stimuli. Here, we propose a signal model for event-related responses in EEG evoked with a rapid sequence of stimuli in BCI applications...

Loudspeaker-based virtual sound environments provide a valuable tool for studying speech perception in realistic, but controllable and reproducible acoustic environments. The evaluation of different loudspeaker reproduction methods with respect to perceptual measures has been rather limited. This study focused on comparing speech intelligibility as measured in a reverberant reference room with virtual versions of that room. Two reproduction methods were based on room acoustic simulations, presented either using mixed-order ambisonics or nearest loudspeaker mapping playback...

The term « cybersex » refers to the use of the Internet for sexual purposes (pornography, webcams, dating). While moderate use of cybersex could have a positive effect on sexual life, a small fraction of these cyber-users could have difficulties to control their consumption with negative consequences. This phenomenon, whose understanding of the mechanisms still raises debates, seems to be influenced by various psychological factors, including avoidant attachment (avoidance of close emotional relationship) and depressed mood...

BACKGROUND: A range of school-based prevention programmes has been developed and used to prevent, delay, or reduce alcohol use among adolescents. Most of these programmes have been evaluated at the community-level impact. However, the effect of contextual risk factors has rarely been considered in the evaluation of these programmes. The aim of this study was to investigate the potential moderating effects of two important contextual risk factors (i.e., socioeconomic status and peer victimisation) on the effectiveness of the school-based personality-targeted interventions (Preventure programme) in reducing adolescent alcohol use over a two-year period using a cluster-randomised trial...

Background: Impulse control disorders in Parkinson's disease (PD) represent emerging problems with potentially devastating consequences. The standard screening methods for impulse control disorders are clinically imperfect. Although it is rarely reported, many patients utilize the Internet to fulfill their compulsive behaviors because of its easy accessibility. We designed a study to test the hypothesis that an active screening for excessive Internet use and Internet addiction might improve the sensitivity of identification of impulse control disorders...

Impulse control disorders (ICDs) in Parkinson's disease (PD) have a high cumulative incidence and negatively impact quality of life. ICDs are influenced by a complex interaction of multiple factors. Although it is now well-recognized that dopaminergic treatments and especially dopamine agonists underpin many ICDs, medications alone are not the sole cause. Susceptibility to ICD is increased in the setting of PD. While causality can be challenging to ascertain, a wide range of modifiable and non-modifiable risk factors have been linked to ICDs...

Background: Prior laboratory findings indicate that training avoidance movements to angry faces may lower anger and aggression among healthy participants, especially those high in trait anger. To enrich this training and make it more suitable for clinical applications, it has been developed into a Virtual Reality Game for Aggressive Impulse Management (VR-GAIME). Methods: The proposed study will examine the effects of this training in a randomized controlled trial among forensic psychiatric outpatients with aggression regulation problems ( N = 60)...

The axonal conduction of action potentials affects the absolute time it takes to transmit nerve impulses as well as temporal summation at destination synapses. At the physiological level, oligodendrocyte depolarization facilitates axonal conduction along myelinated fibers in the hippocampus; however, the functional significance of this facilitation is largely unknown. In this study, we examined the physiology of the facilitation of axonal conduction by investigating the changes in synaptic responses at destination synapses using male and female mice in which channelrhodopsin-2 expression was restricted to oligodendrocytes...

INTRODUCTION: The management of impulse control disorders (ICDs) in Parkinson's disease (PD) relies on their early identification, allowing adjustment of antiparkinsonian treatment before these manifestations lead to major social, financial or legal consequences. The Questionnaire for Impulsive-Compulsive Disorders in Parkinson's Disease-Rating Scale (QUIP-RS) is an English-developed and -validated PD-specific rating scale constructed to support the rating of ICDs and related disorders and the assessment of changes in symptom severity over time, but it has not to date been validated in French...

Predicting subject-specific responses to exoskeleton assistance may aid in maximizing functional gait outcomes, such as achieving full knee-extension at foot contact in individuals with crouch gait from cerebral palsy (CP). The purpose of this study was to investigate the role of volitional and non-volitional muscle activity in subject-specific responses to knee extension assistance during walking with an exoskeleton. We developed a simulation framework to predict responses to exoskeleton torque by applying a stretch-reflex spasticity model with muscle excitations computed during unassisted walking...

Psychological examination aims at objectifying the key symptoms of hyperactivity, namely the disorders of attention and of the exe-cutive functions (briefly, the activation-inhibition control). The -records of 237 patients, aged 5 to 17 and attending our day clinics between 2004 and 2016, are analyzed retrospectively. 40 cases present an attention-deficit/hyperactivity disorder (ADHD), combined presentation, after DSM-5 criteria. These children and adolescents show not only a typical impulsivity on the computerized test of -attention, but also some deficit in learning to write, a precocious manifestation of their neurodevelopmental disorders...

PurposePresent a case of dronabinol-induced hypomania. BACKGROUND: Dronabinol is a synthetic derivative of cannabis that is commonly prescribed for chemotherapy-induced nausea and vomiting or cachexia due to HIV/AIDS. The safety in those with bipolar disorder warrants further investigation as previous studies suggest that the use of cannabis may be associated with exacerbation of manic symptoms. The risk of developing manic symptoms in patients with bipolar disorder who use dronabinol is largely unknown...

Study ObjectivesAlthough stimulants are commonly used for attention-deficit/hyperactivity disorder (ADHD), 10-30% of patients have an inadequate response, adverse events, or comorbidities preventing use. Thus, there is a need for safe, effective nonstimulant options. Extended-release viloxazine (SPN-812), a nonstimulant, is currently in development for the treatment of ADHD in children and adolescents. SPN-812 is a structurally distinct, bicyclic norepinephrine reuptake inhibitor with selective serotonergic activity...

PURPOSE: Emotional eating is important to study and address because it predicts poor outcome in weight loss interventions. Interventions have only touched the surface in terms of addressing emotional eating. Mindfulness approaches can address emotional eating by modification of emotion regulation and appetitive traits. The current study involved development of an emotional eating-specific mindfulness intervention and assessment of its effect on appetitive traits associated with emotional eating...

Outcomes of bariatric surgery, while frequently impressive, are not universal and vary between patients and across surgical procedures. Between 20% and 30% of patients experience suboptimal weight loss or significant weight regain within the first few postoperative years. The reasons for this are not fully understood, but likely involve both physiologic processes, behavioral factors, and psychological characteristics. Evidence suggests that preoperative psychosocial status and functioning can contribute to suboptimal weight losses and/or postoperative psychosocial distress...
