Perspectives from gambling expert stakeholders in relation to electronic gaming machines in New Zealand.

Electronic gaming machines (EGMs) are one of the most addictive and harmful forms of gambling. Gaming machine characteristics, easy accessibility of EGMs and normalisation of gambling behaviour have exacerbated these effects. We conducted a pilot study investigating the perspectives of gambling expert stakeholders on gambling harm and effective harm-minimisation policies regarding EGMs. In-depth individual interviews were undertaken with 14 health professionals working in the addiction sector, academics in the field of gambling and individuals from a range of government and non-government organisations who have an impact on gambling policy making in New Zealand. Five major themes were identified: the need to shift focus from problematic people to the problematic product, the need for a holistic approach to gambling intervention, focus on creating an empowered population, and improving protective factors and refining public health initiatives to gambling harm. The results suggest the need to challenge current narratives of EGM-related gambling harm and have wide-ranging implications for EGM harm minimisation and health promotion policies.

Ketamine uropathy: Clinical experience in a high prevalence center.

OBJECTIVES: Ketamine uropathy causes inflammatory changes to the urothelium, manifesting as significant lower urinary tract symptoms, small bladder capacity, and pelvic pain. Upper tract involvement and hydronephrosis can occur. Data from UK centers are limited, and no formal treatment guidelines exist. PATIENTS AND METHODS: All patients with ketamine uropathy presenting to our unit over an 11-year period were identified through operative and clinic lists, emergency presentations, and a prospectively collected local database. Demographic data, biochemical findings, imaging techniques, and both medical and surgical management were recorded. RESULTS: A total of 81 patients with ketamine uropathy were identified from 2011 to 2022; however, a large proportion presented from 2018 onwards. The average age at presentation was 26 years (interquartile range [IQR]: 27-34), 72.8% were male, and average follow-up time was 34 months (IQR: 8-46). Therapeutic interventions included anticholinergic medication, cystodistension, and intravesical sodium hyaluronate. Hydronephrosis was present in 20 (24.7%) patients and nephrostomy insertion was required in six. One patient underwent bladder augmentation surgery. Serum gamma-glutamyl transferase and length of follow-up were significantly higher in patients with hydronephrosis. Adherence to follow-up was poor. CONCLUSIONS: We present a large cohort of patients with ketamine uropathy from a small town in the UK which is unusual. The incidence appears to be rising, in-keeping with increasing recreational ketamine use and should be of concern to urologists. Abstinence is a key aspect of management, and a multi-disciplinary approach works best particularly as many patients are lost to follow-up. The development of formal guidance would be helpful.

Unusual presentation of a periurethral abscess following infection with Neisseria gonorrhoea.

We describe an unusual case of a male patient presenting with penile and testicular swelling following an unprotected and traumatic sexual encounter. It was suspected that an isolated penile injury occurred during intercourse; however, ultrasound imaging identified an intact tunical layer and right-sided epididymo-orchitis. Following screening for sexually transmitted infections (STIs), he was discharged with antibiotics and advice to attend the Sexual Health Centre for contact tracing. He represented with a periurethral abscess and an antimicrobial-resistant (AMR) strain of Neisseria gonorrhoea was identified. Appropriate antibiotic treatment was initiated. Examination-under-anaesthesia, following abscess drainage, revealed a contained collection with no urethral fistula; however, a flat urethral lesion was seen during urethroscopy. Repeat urethroscopy and biopsy of the lesion indicated polypoid urethritis. Periurethral abscess secondary to gonococcal urethritis is a rare complication, but one that we should be suspicious of, especially with the growing incidence of AMR-STIs.

Concurrent Disorders and Decision-Making in Electronic Gaming Machine Gamblers.

This study aimed to investigate the self-reported measures of concurrent disorders (stress, social anxiety, anxiety, depression and alcohol use) among electronic gaming machine (EGM) gamblers with varying levels of gambling severity and to examine its relationship to decision-making. This cross-sectional study in New Zealand involved an online survey that utilised validated questionnaires to assess self-reported measures of concurrent disorders and the Iowa gambling task (IGT) to analyse decision-making. The study comprised of active EGM gamblers (n = 153) who were divided into two groups: non-problem gambling (NPG, n = 71) and problem gambling (PG, n = 82) based on the cut-off point of the South Oaks Gambling Screen (SOGS). Multiple logistic regression models were performed to analyse co-occurring disorders separately and simultaneously, and a log-linear model was developed to define the associations between significant variables. The first model showed a strong correlation between gambling severity and measures for depression (p < 0.01), anxiety (p < 0.05), stress (p < 0.05) and alcohol use (p < 0.01), however only depression (p < 0.05) and alcohol use (p < 0.01) remained significant in the second model. Further, no association between social anxiety scores and problem gambling was found in this sample of EGM gamblers in both models. On the IGT, EGM gamblers in the PG group performed significantly worse. Further, the presence of poor decision-making was more pronounced with higher depression scores (p < 0.01) across both NPG and PG groups and higher alcohol use scores (p < 0.05) scores in the PG group. The presence of high levels of co-occurring disorders and its link to poor decision-making are important considerations in the treatment paradigm of EGM problem gamblers.

Piliwaiwai: Problem Gambling in Hawai'i.

Gambling is illegal in Hawai'i, but it is accessible through technology (eg, the internet), inexpensive trips to Las Vegas, and illegal gaming such as lottery sales, internet gambling, and sports betting. Where there are opportunities to gamble, there is a probability that problem gambling exists. The social costs of gambling are estimated to be as high as $26,300,000 for Hawai'i. Because no peer-reviewed research on this topic exists, this paper has gathered together anecdotal accounts and media reports of illegal gambling in Hawai'i, the existence of Gamblers Anonymous meetings operating on some of the islands, and an account of workshops on problem gambling that were provided by the author on three Hawaiian Islands. Through these lenses of gambling in Hawai'i, it is suggested that there are residents in Hawai'i who do experience problem gambling, yet it is unknown to what extent. Nonetheless, this paper argues that research and perhaps a public health initiative are warranted.

Antagonists of the human adenosine A2A receptor. Part 1: Discovery and synthesis of thieno[3,2-d]pyrimidine-4-methanone derivatives.

The (-)-(11R,2'S)-enantiomer of the antimalarial drug mefloquine has been found to be a reasonably potent and moderately selective adenosine A(2A) receptor antagonist. Further investigation of this compound has led to the discovery of a series of keto-aryl thieno[3,2-d]pyrimidine derivatives, which are potent and selective antagonists of the adenosine A(2A) receptor. These derivatives show selectivity against the A(1) receptor. Furthermore, some of these compounds have been shown to have in vivo activity in a commonly used model, suggesting the potential for the treatment of Parkinson's disease.

Primary care patients reporting concerns about their gambling frequently have other co-occurring lifestyle and mental health issues.

BACKGROUND: Problem gambling often goes undetected by family physicians but may be associated with stress-related medical problems as well as mental disorders and substance abuse. Family physicians are often first in line to identify these problems and to provide a proper referral. The aim of this study was to compare a group of primary care patients who identified concerns with their gambling behavior with the total population of screened patients in relation to co-morbidity of other lifestyle risk factors or mental health issues. METHODS: This is a cross sectional study comparing patients identified as worrying about their gambling behavior with the total screened patient population for co morbidity. The setting was 51 urban and rural New Zealand practices. Participants were consecutive adult patients per practice (N = 2,536) who completed a brief multi-item tool screening primary care patients for lifestyle risk factors and mental health problems (smoking, alcohol and drug misuse, problem gambling, depression, anxiety, abuse, anger). Data analysis used descriptive statistics and non-parametric binomial tests with adjusting for clustering by practitioner using STATA survey analysis. RESULTS: Approximately 3/100 (3%) answered yes to the gambling question. Those worried about gambling more likely to be male OR 1.85 (95% CI 1.1 to 3.1). Increasing age reduced likelihood of gambling concerns - logistic regression for complex survey data OR = 0.99 (CI 95% 0.97 to 0.99) p = 0.04 for each year older. Patients concerned about gambling were significantly more likely (all p < 0.0001) to have concerns about their smoking, use of recreational drugs, and alcohol. Similarly there were more likely to indicate problems with depression, anxiety and anger control. No significant relationship with gambling worries was found for abuse, physical inactivity or weight concerns. Patients expressing concerns about gambling were significantly more likely to want help with smoking, other drug use, depression and anxiety. CONCLUSION: Our questionnaire identifies patients who express a need for help with gambling and other lifestyle and mental health issues. Screening for gambling in primary care has the potential to identify individuals with multiple co-occurring disorders.

Ultimate restraint considerations in base-isolated bridges

Whether specifically carried on seismic isolation bearings or, as is more usual, supported on normal bridge bearings, bridge decks require displacement control to prevent the deck falling off the supporting structure in strong seismic shaking. Transverse restraint is frequently provided by some form of slack "key" whereas longitudinal movement is often controlled by using the abutments as buffers. Such restraints have to be designed to allow normal differential movements such as are prompted by thermal changes, traffic vibration and braking, or small earthquake shaking, but they must be capable of surviving strong earthquake motion generated displacements. It is a matter of concern lest the protection conferred by the flexible bearings om piers, columns or abutments may be depleted significantly by the effects of shock throughout the bridge as the displacement control is activated. This paper describes progress with an ongoing project involving the mathematical modeling of a simple bridge structure supported on bearings such that the longitudinalnatural period is substantially lengthened from the non-isolated condition. Provision is made for the superstructure to be subjected to longitudinal displacement control as the deck impacts the abutments, or stops provided at the tops of the pier walls or columns, under the action of strong ground motion.(AU)

Mathematical modeling of seismic isolation bearings

This paper described one aspect of an ongoing investigation involving finite element analysis of laminated elastomeric bearings at high shear strains. Two - dimensional finite elements analyses have been undertaken to determine whether the simplifying assumption of a plane strain condition can adequately model elastomeric bearings. Two different finite element codes were used to undertake separate analyses which were compared against each other and to the results of applying formula commonly used in bridge bearing design. It is concluded that two - dimensional analysis can be usefull for sensitivity analyses where the absolute value of stiffness or internal stress is of less interest than the change resulting from varying one or more of the physical characteristic of the bearing (AU)

Finite element analysis of elastomeric bearings

An awareness of the limited understanding of the mechanics of elastomeric bearings under large comprension and shear loads, coupled with the availability of advanced computer codes, prompted a study using finite element tachniques. The analytical results obtained are compared with those obtained using existing simplistic design cocnsiderations and with experimental results of previous tests. The verification that a representative and reliable computer model can be used to study elastomeric bearings allows hitherto imcompletely understood aspects of the behavior of bridge bearings at high strains to be studied.(AU)
