Sports betting is increasing worldwide, with an associated increase in sports betting-related problems. Previous studies have examined risk factors for problem gambling amongst sports bettors and have identified demographic, behavioural, marketing, normative and impulsiveness factors. These studies have generally compared those in problem gambling, or a combination of moderate risk and problem gambling, groups to non-problem gamblers, often due to statistical power issues. However, recent evidence suggests that, at a population level, the bulk of gambling-related harm stems from low risk and moderate risk gamblers, rather than problem gamblers...

PURPOSE: Torpedo maculopathy is a rare lesion of the retinal pigment epithelium. This study set out to look at these lesions in the paediatric population and determine the spectrum and features of the disease. METHODS: The paediatric ophthalmology database was used to identify eight children with torpedo maculopathy between 2012 and 2017. Fundal images and optical coherence tomography (OCT) was used to analyse the cases. RESULTS: Eight patients with torpedo maculopathy were identified, making the prevalence approximately 2 per 100,000 population under 16 years old...

Inorganic arsenic exposure is ubiquitous and both exposure and inter-individual differences in its metabolism have been associated with cardiometabolic risk. The association between arsenic exposure and arsenic metabolism with metabolic syndrome and its individual components, however, is relatively unknown. We used poisson regression with robust variance to evaluate the association between baseline arsenic exposure (urine arsenic levels) and metabolism (relative percentage of arsenic species over their sum) with incident metabolic syndrome and its individual components (elevated waist circumference, elevated triglycerides, reduced HDL, hypertension, elevated fasting plasma glucose) in 1,047 participants from the Strong Heart Family Study, a prospective family-based cohort in American Indian communities (baseline visits in 1998-1999 and 2001-2003, follow-up visits in 2001-2003 and 2006-2009)...

Past studies have identified various risk and protective factors for problem gambling (PG). However, no study has examined the interplay between these factors using a combination of person-centered and variable-centered approaches embedded within a longitudinal design. The present study aimed to (a) identify distinct profiles in early adolescence based on a set of risk factors commonly associated with PG (impulsivity, depression, anxiety, drug-alcohol use, aggressiveness, and antisociality), (b) explore the difference in reported gambling problems between these profiles during midadolescence and early adulthood, and (c) identify family- and peer-related variables that could operate as protective or compensatory factors in this context...

The visual environment is filled with complex, multi-dimensional objects that vary in their value to an observer's current goals. When faced with multi-dimensional stimuli, humans may rely on biases to learn to select those objects that are most valuable to the task at hand. Here, we show that decision making in a complex task is guided by the sparsity bias: the focusing of attention on a subset of available features. Participants completed a gambling task in which they selected complex stimuli that varied randomly along three dimensions: shape, color, and texture...

In several contexts, such as finance and politics, people make choices that are relevant for others but irrelevant for oneself. Focusing on decision-making under risk, we compared monetary choices made for one's own interest with choices made on behalf of an anonymous individual. Consistent with the previous literature, other-interest choices were characterized by an increased gambling propensity. We also investigated choice stochasticity, which captures how much decisions vary in similar conditions. An aspect related to choice stochasticity is how much decisions are tuned to the option values, and we found that this was higher during self-interest than during other-interest choices...

Substance-related and behavioral addictions are extremely prevalent and represent a major public health concern. In the ongoing attempt to understand the addictive personality, contradictory results have arisen from studies that have explored personality traits in different addiction populations. The diversity across addiction types suggests that some of these inconsistencies stem from distinct personalities underlying each addiction. The present study compares the personality profiles of several addictions, representing both substance (drugs and alcohol) and behavioral (gambling and sex) subtypes...

BACKGROUND: Parkinson's disease (PD) patients who are treated with dopamine replacement therapy are at risk of developing impulse control disorders (ICDs) (such as gambling, binge eating, and others). According to recent evidence, compulsive reward seeking in ICDs may arise from an excessive attribution of incentive salience (or 'wanting') to rewards. OBJECTIVES: In this study, we tested this hypothesis in patients with PD who developed binge eating (BE). METHODS: Patients with BE, patients without BE, and healthy controls performed different experimental tasks assessing food liking and wanting...

Addiction is the term employed not only for excess consumption of substances, but also for problem behaviours like eating disorders, pathological gambling, computer addiction and pathological preoccupation with video games and sexual acts. No clear diagnostic criterion has been established with validity for behavioral addictions. Sexual addiction, including addiction to pornography is not included as a separate entity because of a lack of strong empirical evidence in this area. Different scales can be used for assessment of sexual addiction...

Disruption of circadian rhythms is commonly reported in individuals with Alzheimer's disease (AD). Neurons in the primary circadian pacemaker, the suprachiasmatic nucleus (SCN), exhibit daily rhythms in spontaneous neuronal activity which are important for maintaining circadian behavioral rhythms. Disruption of SCN neuronal activity has been reported in animal models of other neurodegenerative disorders; however, the effect of AD on SCN neurophysiology remains unknown. In this study we examined circadian behavioral and electrophysiological changes in a mouse model of AD, using male mice from the Tg-SwDI line which expresses human amyloid precursor protein with the familial Swedish (K670N/M671L), Dutch (E693Q), Iowa (D694N) mutations...

BACKGROUND: Systemic lupus erythematosus (SLE) is associated with cognitive deficit but the exact neural mechanisms remain unclear. PURPOSE: To explore sequential brain activities using functional magnetic resonance imaging (fMRI) during the performance of a decision-making task, and to determine whether serum or clinical markers can reflect the involvement of the brain in SLE. SUBJECTS: Sixteen female SLE patients without overt clinical neuropsychiatric symptoms and 16 healthy controls were included...

Lotteries are one of the most prevalent forms of gambling and generate substantial state revenues. They are also argued to be one of the least harmful forms of gambling. This paper is one of the first to examine exclusive lottery gamblers and compares their gambling patterns and problems as well other associated risky behaviours to those who are not exclusive lottery gamblers. Data were derived from two large surveys conducted with representative adult samples in France (n = 15,635) and Québec (n = 23,896)...

Attention-deficit hyperactivity disorder (ADHD) is characterized by deficits in executive functions and decision making during childhood and adolescence. Contradictory results exist whether altered event-related potentials (ERPs) in adults are associated with the tendency of ADHD patients toward risky behavior. Clinically diagnosed ADHD patients ( n = 18) and healthy controls ( n = 18), aged between 18 and 29 (median 22 Yo), were screened with the Conners' Adult ADHD Rating Scales and assessed by the Mini-International Neuropsychiatric Interview, adult ADHD Self-Report Scale, and by the 60-item HEXACO Personality Inventory...

Research on adolescence gambling over the past twenty years has revealed significant incidence and prevalence rates and highlighted the possible negative effects on an adolescent's well-being. Several risk and protective factors have also been identified. Over the course of the past few years, technological advances have heralded the advent of new avenues for gambling as well as new opportunities to gamble without any direct monetary exchange. This review article examines those established trends as well as the new issues that we are faced with, in order to accurately portray the current challenges in research, prevention, and treatment...

BACKGROUND: The management of noncompressible torso hemorrhage remains a significant issue at the point of injury. Resuscitative endovascular balloon occlusion of the aorta (REBOA) has been used in the hospital to control bleeding and bridge patients to definitive surgery. Smaller delivery systems and wirefree devices may be used more easily at the point of injury by nonphysician providers. We investigated whether independent duty military medical technicians (IDMTs) could learn and perform REBOA correctly and rapidly as assessed by simulation...

BACKGROUND: Despite the strong associations between personality disorders and problem/pathological gambling, few studies have investigated the relationships between personality disorders, problem-gambling severity and suicidal thoughts/behaviors. OBJECTIVES: We examined the relationships between problem-gambling severity and personality disorders among individuals with differing levels of suicidality (none, thoughts alone, attempts). METHODS: We analyzed data from 13,543 participants of the National Epidemiologic Survey of Alcohol and Related Conditions (NESARC) study...

Social changes, such as the expansion of legal forms of gambling, can influence not only the prevalence of gambling, but can also shape the relative importance of genetic and environmental contributions to individual differences in the propensity to gamble. In the present study, I examined differences in the prevalence and in the relative contribution of genetic and environmental factors to gambling involvement in the United States in 1962 versus 2002. The data came from two sources: (1) a survey of 839 17-year-old same-sex twin pairs from the National Merit Scholarship Qualifying Test twin study, and (2) an interview of 477 18- to 26-year-old same-sex twin pairs from Wave III of the National Longitudinal Study of Adolescent to Adult Health...

BACKGROUND: Factors such as ethnicity, gender, and socioeconomic status may play a role in both access to and attrition from bariatric programs before surgery is undertaken. New Zealand (NZ) has high rates of obesity in its Pacific population and the indigenous Māori. These groups also experience poorer health outcomes and therefore have the greatest need for surgery. METHODOLOGY: A retrospective cross-sectional study of 704 people referred for and accepted onto a publicly funded bariatric surgery from 2007 to 2016...

Rabies is an important neglected disease, which kills around 59,000 people a year. Over a third of these deaths are in children less than 15 years of age. Almost all human rabies deaths in Africa and Asia are due to bites from infected dogs. Despite the high efficacy of current rabies vaccines, awareness about rabies preventive healthcare is often low in endemic areas. It is therefore common for educational initiatives to be conducted in conjunction with other rabies control activities such as mass dog vaccination, however there are few examples where the efficacy of education activities has been assessed...
