BACKGROUND: Healthcare renunciation for economic reasons is a major health concern, but it has been scarcely investigated among drug users, even if drug users constitute a vulnerable population in need of medical care. This study investigated associations of healthcare renunciation for economic reasons and addictive behaviors (alcohol, tobacco, cannabis, illicit drug use, and gambling) in a population-based sample of adults living in France, a country with universal health coverage. METHODS: Data were collected using the 2014 Health Barometer, a French cross-sectional survey conducted among a random representative sample of the general population aged 18-64 (n=12,852)...

In their debate contribution, Aarseth et al. (2016) strongly argue against the proposal of WHO ICD-11 (International Classification of Diseases, 11th revision) to include Gaming Disorder as a new diagnostic category emphasizing the fact that no consensus exists on the definition and the risk that gaming will be demonized and gamers stigmatized resulting in a tsunami of false positive referrals to treatment. In this commentary, it is argued that gaming is indeed just another relatively innocent recreational activity with only a small minority losing control resulting in gaming-related problems...

CONTEXT: Regulations for quiet urban areas are typically based on sound level limits alone. However, the nonacoustic context may be crucial for subjective soundscape quality. AIMS: This study aimed at comparing the role of sound level and nonacoustic context for subjective urban soundscape assessment in the presence of the full on-site context, the visual context only, and without context. MATERIALS AND METHODS: Soundscape quality was evaluated for three recreational urban spaces by using four subjective attributes: loudness, acceptance, stressfulness, and comfort...

Although it has been widely accepted that Mg has a positive effect on muscle function, studies on the efficacy of Mg supplementation in young athletes have generated contrasting results. The aim of this work was to examine the effect of Mg supplementation on muscular damage markers and the association between serum Mg levels with these muscular markers. Twelve elite male basketball players (PB) from a team of Spanish Professional Basketball League and a control group (CG) comprising twelve university students who practiced regularly recreational basketball and competed in minor university leagues participated in this study...

Research data is a dynamic and evolving entity and the ability to cite such data depends on recreating the same datasets utilized in the original research. Despite the availability of several existing technologies, most data repositories lack the necessary setup to recreate a point-in-time snapshot of data, let alone long-term sustainability of dynamic data without restoring an entire database. Through this project, we adopted a subset of the Research Data Alliance data citation working group recommendations to establish a robust informatics system supporting dynamic data and its use for reproducible research within our evolving clinical data repository...

Marijuana is the most widely abused "recreational" substance in the United States, with highest prevalence in young adults. It is reported to cause ischemic strokes, hepatitis, anxiety, and psychosis. Although it is associated with dose dependent tachycardia and can lead to coronary vasospasm, it has not been directly related to acute myocardial infarction (AMI). Marijuana induced coronary vasospasm can result in endothelial denudation at the site of a vulnerable atherosclerotic plaque in response to hemodynamic stressors, potentially causing an AMI...

INTRODUCTION: Caregivers often experience stressful situations while in the midst of the caregiving process. Thus, various methods of coping have been widely applied and studied in previous researches. The aim of this study was to develop a novel questionnaire to assess the coping strategies employed by those who provide care to patients, and to further validate it among caregivers of schizophrenia patients in Malaysia. METHODS: This study, which involved the caregivers of schizophrenia patients from a hospital in Kuala Lumpur, Malaysia, was comprised of three parts, namely in-depth interviews, a pilot study, and the validation of the developed questionnaire, known as Caregiver Cope (CgCope(TM))...

OBJECTIVE: The spread of new psychoactive substances (NPS) has expanded rapidly in the last decade. The complexity of the pharmacological effects of NPS challenges the traditional treatment guidelines, and information of the emergence of new arrivals is valuable. Our knowledge on the actual range of recreational drugs used and NPS available in Denmark is limited as identification is possible only when consumers become patients in the healthcare system or through drug seizures. We aimed to detect classical recreational drugs and NPS in the urine of music festival attendees and evaluate if the use of NPS could have been predicted by comparing study data with drug seizure data from the previous year published by European and Danish health authorities...

INTRODUCTION: Flibanserin is a medication recently approved by the FDA for treatment of generalized hypoactive sexual desire disorder (HSDD) in premenopausal women. Its mechanism of action is not fully understood but is thought to modulate serotonin receptors and increase levels of norepinephrine and dopamine. While much is known about toxicity of other drugs which affect these systems, there is little information about toxicity of flibanserin at this time. CASE: We present a case of a 2-year-old boy who ingested an estimated 600 mg of his mother's flibanserin...

Robotic lower limb exoskeletons are becoming increasingly popular in therapy and recreational use. However, most exoskeletons are still rather limited in their locomotion speed and the activities of daily live they can perform. Furthermore, they typically do not allow for a dynamic adaptation to the environment, as they are often controlled with predefined reference trajectories. Inspired by human leg stiffness modulation during walking, variable stiffness actuators increase flexibility without the need for more complex controllers...

In this paper, we explore how the integration of auditory and visual cues can help teach the timing of motor skills for the purpose of motor function rehabilitation. We conducted a study using Amazon's Mechanical Turk in which 106 participants played a virtual therapy game requiring wrist movements. To validate that our results would translate to trends that could also be observed during robotic rehabilitation sessions, we recreated this experiment with 11 participants using a robotic wrist rehabilitation system as means to control the therapy game...

Robotics is increasing in popularity as a method of providing rich, personalized and cost-effective physiotherapy to individuals with some degree of upper limb paralysis, such as those who have suffered a stroke. These robotic rehabilitation systems are often high powered, and exoskeletal systems can attach to the person in a restrictive manner. Therefore, ensuring the mechanical safety of these devices before they come in contact with individuals is a priority. Additionally, rehabilitation systems may use novel sensor systems to measure current arm position...
