Abstract
Videoconferencing at a bandwidth of 384 kbit/s was used in open sessions for subjects with alcohol use disorders (AUD). Study participants received eight sessions of group therapy over a four-week period from an accredited addictions counsellor. Outcome assessment included self-report measures, a qualitative interview and a chart review. Of the 18 subjects who started the study, 14 attended at least four sessions of therapy, completed self-report assessments and the thematic interview. The participants reported high levels of satisfaction with telepsychiatry, found the intervention to be highly credible, had good session attendance and attrition comparable to that expected with conventional same-room treatment. In all, 82% of subjects reported that they would recommend the service to a friend or family member. The results demonstrate the feasibility of using videoconferencing for service delivery to adults with AUD, and encourage the future performance of randomized controlled trials.

Abstract
BACKGROUND Previous studies reported that repetitive transcranial magnetic stimulation (rTMS) can reduce cue-elicited craving and decrease cigarette consumption in smokers. The mechanism of this effect however, remains unclear. We used resting-state functional magnetic resonance imaging (rsfMRI) to test the effect of rTMS in non-treatment seeking smokers. METHODS We used a single blinded, sham-controlled, randomized counterbalanced crossover design where participants underwent two visits separated by at least 1 week. Participants received active rTMS over the left dorsolateral prefrontal cortex (DLPFC) during one of their visits, and sham rTMS during their other visit. They had two rsFMRI scans before and after each rTMS session. We used the same rTMS stimulation parameters as in a previous study (10Hz, 5s-on, 10s-off, 100% resting motor threshold, 3000 pulses). RESULTS Ten non-treatment-seeking, nicotine-dependent, cigarette smokers (6 women, an average age of 39.72 and an average cigarette per day of 17.30) finished the study. rsFMRI results demonstrate that as compared to a single session of sham rTMS, a single session of active rTMS inhibits brain activity in the right insula and thalamus in fractional amplitude of low frequency fluctuation (fALFF). For intrinsic brain connectivity comparisons, active TMS resulted in significantly decreased connectivity from the site of rTMS to the left orbitomedial prefrontal cortex. CONCLUSIONS This data suggests that one session of rTMS can reduce activity in the right insula and right thalamus as measured by fALFF. The data also demonstrates that rTMS can reduce rsFC between the left DLPFC and the medial orbitofrontal cortex.

Abstract
UNLABELLED Shiga toxin-producing Escherichia coli (STEC) is an important foodborne pathogen that can cause hemorrhagic colitis and hemolytic-uremic syndrome. Cattle are the primary reservoir for STEC, and food or water contaminated with cattle feces is the most common source of infections in humans. Consequently, we conducted a cross-sectional study of 1,096 cattle in six dairy herds (n = 718 animals) and five beef herds (n = 378 animals) in the summers of 2011 and 2012 to identify epidemiological factors associated with shedding. Fecal samples were obtained from each animal and cultured for STEC. Multivariate analyses were performed to identify risk factors associated with STEC positivity. The prevalence of STEC was higher in beef cattle (21%) than dairy cattle (13%) (odds ratio [OR], 1.76; 95% confidence interval [CI], 1.25, 2.47), with considerable variation occurring across herds (range, 6% to 54%). Dairy cattle were significantly more likely to shed STEC when the average temperature was >28.9°C 1 to 5 days prior to sampling (OR, 2.5; 95% CI, 1.25, 4.91), during their first lactation (OR, 1.8; 95% CI, 1.1, 2.8), and when they were <30 days in milk (OR, 3.9; 95% CI, 2.1, 7.2). These data suggest that the stress or the negative energy balance associated with lactation may result in increased STEC shedding frequencies in Michigan during the warm summer months. Future prevention strategies aimed at reducing stress during lactation or isolating high-risk animals could be implemented to reduce herd-level shedding levels and avoid transmission of STEC to susceptible animals and people. IMPORTANCE STEC shedding frequencies vary considerably across cattle herds in Michigan, and the shedding frequency of strains belonging to non-O157 serotypes far exceeds the shedding frequency of O157 strains, which is congruent with human infections in the state. Dairy cattle sampled at higher temperatures, in their first lactation, and early in the milk production stage were significantly more likely to shed STEC, which could be due to stress or a negative energy balance. Future studies should focus on the isolation of high-risk animals to decrease herd shedding levels and the potential for contamination of the food supply.

Abstract
OBJECTIVES A high degree of de-regulation, organisational fragmentation and funding cuts throughout UK schools in recent years has obscured the definitive structure and effectiveness of physical activity (PA) provision offered to children. This pilot study aimed to map the current structure and context of PA provision offered to school children in Southampton, and its alignment with existing empirical evidence about the likely effectiveness of such interventions. STUDY DESIGN Utilising a qualitative approach, the study focused upon school-based PA provision, since this setting was conjectured to show greater diversity when compared to settings outside of school, lending itself to further interventions than non-school PA provision. METHODS Interventions offered across nine schools (three junior, two primary, four secondary) were investigated and mapped through semi-structured interviews. Findings were benchmarked against other cities similar to Southampton in indices of multiple deprivation status via interviews with city council workers. RESULTS Interviews highlighted only three formal PA specific interventions currently operating, and a hand full of informal interventions. Limited PA provision was attributed to a lack of time, money, and priority devoted towards PA within schools. Considerable disparity exists between the high prevalence of sport-oriented provision compared with the low prevalence of PA specific provision. Interviews with Portsmouth and Bristol city councils suggest that such findings may not be unique to Southampton. CONCLUSIONS In contrast to the extensive literature base detailing numerous PA interventions in school-aged children, our data suggest that a very small amount of such knowledge appears to translate into PA provision offered in Southampton schools. Our data highlight a significant discrepancy between sport and PA provision across schools. It is possible that the inability to successfully differentiate between sport and PA may present a further obstacle to the successful uptake of PA in the future. An extension of the PA mapping carried out, both countywide and nationally, provides a possible avenue for future research to confirm or contrast these initial insights.

Abstract
BACKGROUND Neuroimaging of drug-associated cue presentations has aided in understanding the neurobiological substrates of craving and relapse for cocaine, alcohol, and nicotine. However, imaging of cue-reactivity in methamphetamine addiction has been much less studied. METHOD Nine caucasian male methamphetamine-dependent subjects and nine healthy controls were scanned in a Phillips 3.0T MRI scan when they viewed a randomized presentation of visual cues of methamphetamine, neutral objects, and rest conditions. Functional Imaging data were analyzed with Statistical Parametric Mapping software 5 (SPM 5). RESULTS Methamphetamine subjects had significant brain activation in the ventral striatum and medial frontal cortex in comparison to meth pictures and neutral pictures in healthy controls (p<0.005, threshold 15 voxels). Interestingly the ventral striatum activation significantly correlated with the days since the last use of meth (r=-0.76, p=0.017). No significant activity was found in healthy control group. CONCLUSION The preliminary data suggest that methamphetamine dependent subjects, when exposed to methamphetamine-associated visual cues, have increased brain activity in ventral striatum, caudate nucleus and medial frontal cortex which subserve craving, drug-seeking, and drug use.

Abstract
OBJECTIVE This campaign sought to (a) increase awareness of sexual health and chlamydia testing; (b) motivate students, particularly sexually active men who do not pursue regular sexually transmitted infection (STI) testing, to get tested; and (c) improve the capacity of the student health center to provide free chlamydia testing and treatment for all students. PARTICIPANTS Students enrolled at a 4-year public research university (N = 333). METHODS Collaborative partnerships formed the foundation of a campus marketing and testing campaign, with treatment for students testing positive for chlamydia. RESULTS A total of 333 students were tested over 5 consecutive Mondays, showing a chlamydia incidence of 9.6%. The incidence for females and males were 8.6% and 10.8%, respectively. CONCLUSIONS The campaign was effective in reaching men, an at-risk population not traditionally emphasized in STI testing.

Abstract
Herein we describe a series of tetrahydrobenzotriazoles as novel, potent metabotropic glutamate receptor subtype 5 (mGlu5) positive allosteric modulators (PAMs). Exploration of the SAR surrounding the tetrahydrobenzotriazole core ultimately led to the identification of 29 as a potent mGlu5 PAM with a low maximal glutamate potency fold shift, acceptable in vitro DMPK parameters and in vivo PK profile and efficacy in the rat novel object recognition (NOR) assay. As a result 29 was identified as a suitable compound for progression to in vivo safety evaluation.

Abstract
AIMS Functional magnetic resonance imaging research has attempted to elucidate the neurobehavioral underpinnings of cocaine dependence by evaluating differences in brain activation to cocaine and response inhibition cues between cocaine-dependent individuals and controls. This study investigated associations between task-related brain activation and cocaine use characteristics. DESIGN Cross-sectional. SETTING The Center for Biomedical Imaging at the Medical University of South Carolina, USA. PARTICIPANTS Fifty-one cocaine users (41 dependent). MEASUREMENTS Brain activation to cocaine-cue exposure and Go No-Go tasks in six a priori selected brain regions of interest and cocaine use characteristics (i.e. cocaine dependence status, years of cocaine use, cocaine use in the past 90 days) assessed via standardized interviews. FINDINGS Participants demonstrated elevated activation to cocaine (bilateral ventral striatum, dorsal caudate, amygdala) and response inhibition (bilateral anterior cingulate, insula, inferior frontal gyrus) cues in all hypothesized brain regions. Years of cocaine use was associated with task-related brain activation, with more years of cocaine use associated with greater activation to cocaine cues in right (F = 7.97, P = 0.01) and left (F = 5.47, P = 0.02) ventral striatum and greater activation to response inhibition cues in left insula (F = 5.10, P = 0.03) and inferior frontal gyrus (F = 4.12, P = 0.05) controlling for age, cocaine dependence status and cocaine use in the past 90 days. CONCLUSIONS Years of cocaine use may be more centrally related to cocaine cue and response inhibition brain activation than cocaine dependence diagnosis or amount of recent use.
