RESUMO
Gambling and its impacts are an important public health issue. The relationship between gambling, problem gambling and gambling harm is complex and dynamic. Replicate prevalence studies are useful for surveillance and monitoring gambling impacts within jurisdictions. The purpose of this study was to compare changes in gambling and problem gambling in the Victorian adult population between 2008 and 2018 by investigating individual gambling activities and exploring their relationship with the Victorian gambling ecosystem. Gambling participation has decreased; problem gambling prevalence has not. Investigation beyond these summary measures reveals important details: (a) Electronic Gaming Machines (EGMs), casino table games, race and sports betting ('high-risk activities'), informal private betting, and Keno, and their associations with problem gambling endure. Further, the strength of this association is unaffected by changes in product technology, delivery, or the Victorian environment in which they reside, (b) participation in high-risk activities, excluding EGMs, increased while for other activities they decreased, (c) EGMs continue to pose the greatest risk for Victorians, (d) males and young adults continue having a higher problem gambling prevalence rate and preferring both online gambling and high-risk activities (excluding racing favoured by an ageing, older cohort, and Keno, by all ages), and (e) gambling access and exposure proliferated enabling single site multiple gambling opportunities on high-risk activities. Young adults represented a new vulnerable group as they reach the legal gambling age. The most effective interventions (based on major falls in real expenditure (losses) on EGMs, the highest risk activity) were the smoking bans, removal of ATMs from venues and decreases in bet size. There is great potential for prevention, intervention, and minimising harm in the gambling environment.
RESUMO
The challenges facing tree orchard production in the coming years will be largely driven by changes in the climate affecting the sustainability of farming practices in specific geographical regions. Identifying key traits that enable tree crops to modify their growth to varying environmental conditions and taking advantage of new crop improvement opportunities and technologies will ensure the tree crop industry remains viable and profitable into the future. In this review article we 1) outline climate and sustainability challenges relevant to horticultural tree crop industries, 2) describe key tree crop traits targeted for improvement in agroecosystem productivity and resilience to environmental change, and 3) discuss existing and emerging genomic technologies that provide opportunities for industries to future proof the next generation of orchards.
RESUMO
Background: Evidence is lacking for safe and effective treatments for juvenile localised scleroderma (JLS). Methotrexate (MTX) is commonly used first line and mycophenolate mofetil (MMF) second line, despite a limited evidence base. A head to head trial of these two medications would provide data on relative efficacy and tolerability. However, a frequentist approach is difficult to deliver in JLS, because of the numbers needed to sufficiently power a trial. A Bayesian approach could be considered. Methods: An international consensus meeting was convened including an elicitation exercise where opinion was sought on the relative efficacy and tolerability of MTX compared to MMF to produce prior distributions for a future Bayesian trial. Secondary aims were to achieve consensus agreement on critical aspects of a future trial. Results: An international group of 12 clinical experts participated. Opinion suggested superior efficacy and tolerability of MMF compared to MTX; where most likely value of efficacy of MMF was 0.70 (95% confidence interval (CI) 0.34-0.90) and of MTX was 0.68 (95% CI 0.41-0.8). The most likely value of tolerability of MMF was 0.77 (95% CI 0.3-0.94) and of MTX was 0.62 (95% CI 0.32-0.84). The wider CI for MMF highlights that experts were less sure about relative efficacy and tolerability of MMF compared to MTX. Despite using a Bayesian approach, power calculations still produced a total sample size of 240 participants, reflecting the uncertainty amongst experts about the performance of MMF. Conclusions: Key factors have been defined regarding the design of a future Bayesian approach clinical trial including elicitation of prior opinion of the efficacy and tolerability of MTX and MMF in JLS. Combining further efficacy data on MTX and MMF with prior opinion could potentially reduce the pre-trial uncertainty so that, when combined with smaller trial sample sizes a compelling evidence base is available.
