Disordered gambling and many eating disorders (EDs) involve recurrent loss of impulse control. We examined rates of specific EDs, ED psychopathology, substance use disorders, and their interrelationships with impulsiveness among community members with disordered gambling. Community-recruited adults with pathological (n?=?95) or problem (n?=?9) gambling (N?=?104; 51% female) completed structured interviews and questionnaires. We observed high rates of substance dependence, lifetime EDs, and current ED psychopathology; 20.8% of women (vs 1.9% of men) had a DSM-IV ED, and 37.8% (vs 3.9%) had an ED according to proposed DSM-5 criteria. Although disordered gambling severity was not associated with ED diagnosis or severity of ED psychopathology, greater disordered gambling severity and an ED diagnosis were both associated with increased impulsiveness. These findings suggest that impulsiveness might constitute a common personality characteristic that underlies disordered gambling and EDs.

BACKGROUND: Childhood obesity is a growing problem in America. Orthopaedic surgeons have an opportunity to interact with communities to educate children about healthy eating and physical activity. The American Academy of Orthopedic Surgeons (AAOS) Leadership Fellows Program [1] Class of 2012 created a presentation for AAOS members to bring to local schools. The goal was to teach the children about the potential complications of childhood obesity and the benefits of healthy living. QUESTIONS/PURPOSES: We describe a program in which orthopaedic surgeons gave presentations to elementary school students about healthy eating and activity and the effects that extra weight can have on their bones. METHODS: Each of the five members of the Leadership Fellows Program [1] 2012 class (JW, EM, MP, MR, MF) presented to a school in his or her hometown. The program was presented to 210 fifth grade children throughout the country. Before and after the presentation, students took a six-question multiple-choice quiz and answers compared to assess improvement in knowledge. RESULTS: The average number of answers correct before the presentation was 4.5 out of six, and the average after the presentation was six of six. The presentations were well received, and the students and their teachers invited each presenter back the next year. CONCLUSIONS: The improvement in quiz scores demonstrated interest among the students in that they paid attention and understood the content. The children appeared enthusiastic to learn about this subject, and the schools were enthusiastic to include the curriculum.

The influence of stress at puberty on mood and learning: Role of the ?4?? GABA(A) receptor.

It is well-known that the onset of puberty is associated with changes in mood as well as cognition. Stress can have an impact on these outcomes, which in many cases, can be more influential in females, suggesting that gender differences exist. The adolescent period is a vulnerable time for the onset of certain psychopathologies, including anxiety disorders, depression and eating disorders, which are also more prevalent in females. One factor which may contribute to stress-triggered anxiety at puberty is the GABA(A) receptor (GABAR), which is known to play a pivotal role in anxiety. Expression of ?4?? GABARs increases on the dendrites of CA1 pyramidal cells at the onset of puberty in the hippocampus, part of the limbic circuitry which governs emotion. This receptor is a sensitive target for the stress steroid THP (3?-OH-5[?]?-pregnan-20-one), which paradoxically reduces inhibition and increases anxiety during the pubertal period (?PND 35-44) of female mice in contrast to its usual effect to enhance inhibition and reduce anxiety. Spatial learning and synaptic plasticity are also adversely impacted at puberty, likely a result of increased expression of ?4?? GABARs on the dendritic spines of CA1 hippocampal pyramidal cells, which are essential for consolidation of memory. This review will focus on the role of these receptors in mediating behavioral changes at puberty. Stress-mediated changes in mood and cognition in early adolescence may have relevance for the expression of psychopathologies in adulthood.
